Description:
ELECTROCHROMIC DEVICES AND COMPOSITIONS INCLUDING CATHODIC ZWITTERIONS CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is entitled to and claims priority to United States Provisional Patent Application No. 63/333,234, which was filed on April 21, 2022, and United States Nonprovisional Patent Application No. 18/130,932, which was filed on April 5, 2023, the disclosures of which, in each case, are incorporated herein by reference in their entirety. FIELD [0002] The present invention relates to electrochromic devices and compositions that include a cathodic component that includes cathodic zwitterions, where an anion is covalently bonded by a divalent linking group to a pyridinium nitrogen of the cathodic component. BACKGROUND [0003] Electrochromism involves a reversible change in a material’s visible color and/or transmittance of visible light with the application of an electrical potential. The change in color and/or transmittance typically involves alternately cycled oxidized and reduced charge states. Generally, a material that generates a color while undergoing reduction is referred to as a cathodically-coloring electrochromic material; and a material that generates color while undergoing oxidation is referred to as an anodically-coloring electrochromic material. [0004] Electrochromic devices typically include opposed electrodes (e.g., an anode and a cathode) having interposed there-between an electrochromic layer that is solution or gel-based. The kinetics of such electrochromic devices is typically governed primarily by mass transport of cathodic components and anodic components across and through the electrochromic layer. With some electrochromic systems, the cathodic component is positively charged, and the anodic component is neutral or non-charged. With such systems, the positively charged cathodic component is typically transported at a higher rate across the electrochromic layer towards the cathode, than is the non-charged anodic component as it diffuses towards the anode. Such a transport imbalance can result in undesirably increased overpotentials at the anodic interface and correspondingly overoxidation. Overoxidation can undesirably result in reduced durability of the electrochromic device. [0005] It would be desirable to develop new electrochromic devices and compositions in which the active components thereof, and in particular, the cathodic and anodic components, provide improved mass transport balance. It would be further desirable that such newly developed electrochromic devices and compositions provide, or otherwise have associated therewith, improved durability, reduced costs of manufacture and/or operation, and/or improved efficiency of operation. SUMMARY [0006] In accordance with the present invention, there is provided an electrochromic device comprising: (a) a first substrate having a surface comprising a first transparent electrode layer; (b) a second substrate having a surface comprising a second transparent conductive electrode layer, wherein the first transparent electrode layer and the second transparent electrode layer are in opposing spaced opposition; and (c) an electrochromic layer interposed between the first transparent electrically conductive electrode layer and the second transparent electrically conductive electrode layer.

[0009] In accordance with the present invention, there is further provided an electrochromic composition comprising: (i) a cathodic component; (ii) an anodic component; (iii) an optional electrolyte; (iv) a polymeric thickener; and (v) a solvent. The cathodic component, of the electrochromic composition, comprises a cathodic component having cationic charge selected from at least one of a 1,1’-disubstituted-4,4’-dipyridinium cation represented by Formula (I) as provided above, or a 1,1-(alkane-alpha, omega-diyl)-bis-(1'- substituted-4,4'-dipyridinium) cation represented by Formula (II) as provided above.

[0015] Unless otherwise indicated, all ranges or ratios disclosed herein are to be understood to encompass any and all values, and subranges or subratios subsumed therein. For example, a stated range or ratio of "1 to 10" should be considered to include any and all values there- between (such as, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10), and subranges between (and inclusive of) the minimum value of 1 and the maximum value of 10; that is, all subranges or subratios beginning with a minimum value of 1 or more and ending with a maximum value of 10 or less, such as but not limited to, 1 to 6.1, 3.5 to 7.8, and 5.5 to 10. [0016] As used herein, unless otherwise indicated, left-to-right representations of linking groups, such as divalent linking groups, are inclusive of other appropriate orientations, such as, but not limited to, right-to-left orientations. For purposes of non-limiting illustration, the left- to-right representation of the divalent linking group or equivalently - C(O)O-, is inclusive of the right-to-left representation thereof, , or equivalently -O(O)C- or -OC(O)-. [0017] Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as modified in all instances by the term “about.” [0018] As used herein, molecular weight values of polymers, such as weight average molecular weights (Mw) and number average molecular weights (Mn), are determined by gel permeation chromatography using appropriate standards, such as polystyrene standards.

[0022] As used herein, the term “electrochromic” and similar terms, such as “electrochromic compound” means having an absorption spectrum for at least visible radiation that varies in response to the application of an electric potential. Further, as used herein the term “electrochromic material” means any substance that is adapted to display electrochromic properties (such as, adapted to have an absorption spectrum for at least visible radiation that varies in response to an applied electric potential) and which includes at least one electrochromic compound. [0023] As used herein, the term “electric potential” and related terms such as “electrical potential” means an electric potential that is capable of causing a response in a material, such as, but not limited to, transforming an electrochromic material from one form or state to another, as will be discussed in further detail herein.

It is to be understood, however, that the invention can assume various alternative orientations and, accordingly, such terms are not to be considered as limiting. [0029] As used herein, the terms "formed over,” "deposited over," "provided over," “applied over,” residing over,” or “positioned over,” mean formed, deposited, provided, applied, residing, or positioned on but not necessarily in direct (or abutting) contact with the underlying element, or surface of the underlying element. For example, a layer "positioned over" a substrate does not preclude the presence of one or more other layers, coatings, or films of the same or different composition located between the positioned or formed layer and the substrate. [0030] As used herein, the terms “interposed” and “interposed between,” mean residing or positioned between, but not necessarily in direct (or abutting) contact with overlying and/or underlying elements, or surfaces thereof. For example, a layer “interposed between” a first substrate and a second substrate does not preclude the presence of one or more other layers, coatings, or films of the same or different composition located between the interposed layer and the first and/or second substrates.

In accordance with some embodiments of the present invention, formation of the electrochromic composition and electrochromic layer includes the following steps. First, all components of the electrochromic composition, other than the polymeric thickener, are mixed under sheer (such as with an impeller) until a homogenous mixture is formed. Secondly, the polymeric thickener is added, and the combination is subjected to homogenization, which results in the formation of a thick slurry. A liquid film of the thick slurry is formed, such as using a doctor blade or draw-down bar, on a sacrificial or temporary liner (composed of polyethylene terephthalate, in some embodiments). The liquid film while on the sacrificial / temporary liner is subjected to elevated temperature, such as from 60° to 90°C for 3 to 10 minutes, which results in the formation of a solidified film / layer, which is the electrochromic layer. The solidified film / electrochromic layer, is separated from the sacrificial / temporary liner (which is discarded), cut to size (if necessary), and placed over or onto a first transparent electrode layer of a first substrate. The second transparent electrode of a second substrate is positioned over or onto the other (or facing / exposed) side of the electrochromic layer, to form a stack that includes the first substrate, the first transparent electrode, the electrochromic layer, the second transparent electrode, and the second substrate. The stack may further include electrical connectors that are in separate electrical contact with the first and second transparent electrodes. The stack (with an optional gasket surrounding the outer edges of at least the electrochromic layer) is subjected to vacuum lamination, with the concurrent application of elevated temperature, such as from 110°C to 200°C, for a period of time, such as from 10 to 30 minutes. After cooling, the so formed electrochromic device is removed from vacuum lamination device. [0136] In accordance with some further embodiments, when the polymeric thickener of the electrochromic composition includes, or is, poly(diallyldimethylammonium X-), as described previously herein, the electrochromic layer can be prepared therefrom in accordance with the following general description. First, all components of the electrochromic composition, other than the polymeric thickener, are mixed under sheer (such as with an impeller) until a homogenous mixture is formed. Secondly, the polymeric thickener is added and mixed to form a viscous paste. The viscous paste is compounded and extruded at elevated temperature into the desired form, such as a film (in some embodiments this can be accomplished through a heated extrusion screw and slot die). This film can be deposited onto a sacrificial or temporary liner (e.g., composed of polyethylene terephthalate, in some embodiments) or extruded directly onto a first transparent electrode layer of a first substrate. For embodiments that use a sacrificial liner, the film / electrochromic layer, is then separated from the sacrificial / temporary liner (which is discarded), cut to size (if necessary), and placed over or onto a first transparent electrode layer of a first substrate. The second transparent electrode of a second substrate is positioned over or onto the other (or facing / exposed) side of the electrochromic layer, to form a stack that includes the first substrate, the first transparent electrode, the electrochromic layer, the second transparent electrode, and the second substrate. The stack can optionally further include electrical connectors that are in separate electrical contact with the first and second transparent electrodes. The stack (with an optional gasket surrounding the outer edges of at least the electrochromic layer) is subjected to vacuum lamination, with the concurrent application of elevated temperature, such as from 110°C to 200°C, for a period of time, such as from 10 to 30 minutes.

[0172] The present invention is more particularly described in the following examples, which are intended as illustrative only, since numerous modifications and variations therein will be apparent to those skilled in the art. EXAMPLES [0173] In Part-1 of the examples there is described the synthesis of anodic components having an anion covalently bonded thereto, according to the present invention. In Part-2 there is described the synthesis of cathodic components according to the present invention. In Part- 3 there is described the preparation of a poly(diallyldimethylammonium X-) polymer according to the present invention. In Part-4, the preparation of an electrochromic device according to the present invention is described. In Part-5, the evaluation of the electrochromic device of Part-4 is described. Part-1 Synthesis Example 1 [0174] With reference to Scheme-(1) below, there is provided a non-limiting description of the preparation of an anodic component having an anion covalently bonded thereto according to the present invention represented by Formula (V), where R 9 is a divalent n- propane linking group. [0175] Into an oven dried 3-neck, 500 ml round bottomed flask with magnetic stirring was added 200 mL of dimethylformamide (DMF) and 10 g of (1) phenothiazine (50.2 mmol). The solution was stirred while being purge with nitrogen for 1 hour. To the reaction mixture was added 2.4 g of 60% NaH (60 mmol). The solution was observed to turn deep red as bubbles were produced therefrom. After continuous mixing under nitrogen for one hour, the production of bubbles was observed to cease. While under a nitrogen sweep is 6.6 g of (2) 1,3- propanesultone (55.2 mmol) dissolved in 10 g of dry DMF, was added drop-wise to the contents of the flask. After completion of the addition of (2) 1,3-propanesultone, the reaction mixture was left to stir at room temperature for 18 hours under nitrogen. [0176] The reaction was quenched by the addition of 100 mL of deionized (DI) water and the solvent was removed by the application of vacuum, after which an oily substance remained in the flask. To the oily substance was added 50 mL of ethyl acetate, which resulted in the formation of a precipitate that was collected by vacuum filtration. The precipitate was washed with cold ethyl acetate and dried overnight under vacuum at 60°C to yield the desired product (3) sodium 3-(10H-phenothiazin-10-yl)-propane-1-sulfonate, as an off-white solid. Scheme-(1) Part-1 Synthesis Example 2 [0177] With reference to Scheme-(2) below, there is provided a non-limiting description of the preparation of an anodic component having an anion covalently bonded thereto according to the present invention represented by Formula (VI), where R 10 is a divalent n- propane linking group, and R 11 is trifluoromethyl. [0178] The (3) sodium 3-(10H-phenothiazin-10-yl)-propane-1-sulfonate was prepared in accordance with Synthesis Example 1. One gram (0.0029 mol) of (3) sodium 3-(10H- phenothiazin-10-yl)propane-1-sulfonate was fine ground with mortar and pestle, and then placed in a 100 ml round-bottom flask equipped with a magnetic stir bar and a reflux condenser with a N 2 sweep / blanket. Acetone in an amount of 20 ml and 40 mg of 18-crown-6 ether were added to the flask and the mixture was stirred vigorously for 15 minutes. The solution turned cloudy, but solid sodium salt (3) was observed to be present. (4) Cyanuric chloride (540 mg, 0.0029 mol, 1 equiv.) was added under vigorous stirring under N 2 . The mixture was refluxed for 24 hours on an oil bath (at about 80°C). The color of the solution turned orange and a fine precipitate formed. Large chunks of initial Na salt (3) were no longer observable. Thin layer chromatography (TLC) showed the presence of a single reaction product that turned pink upon exposure to short-wave (316 nm) UV in air, evidencing formation of (5) 3-(10H-phenothiazin- 10-yl)-propane-1-sulfonyl chloride. The product (5) was fairly mobile in 50:50 EtOAc/Hexanes. The reaction mixture was cooled to room temperature and filtered through a thin layer of alumina. The solvent was removed under vacuum to give 1.25 g of orange-yellow glassy solid (5). The product (5) was dissolved in MeCN and the solids were filtered off. The filtrate was used in the next step without additional purification. [0179] (6) Trifluoromethylsulfonamide (4.53 g, 0.0305 mol, 1.05 equiv.) and potassium carbonate (40 g, 0.29 mol, 10 equiv.) were placed in a 500 ml 3-neck flask equipped with a reflux condenser, magnetic stir bar and a fritted Schlenk funnel. Nitrogen feeds were attached to the condenser and the Schlenk funnel and secured with plastic clips. An intense nitrogen flux was used to flush the vessel for 15 seconds, and a septum was installed in the remaining neck. Anhydrous MeCN in an amount of 100 ml was added through the septum using a syringe. The mixture was vigorously stirred for 20 minutes, yielding a white hazy dispersion. To the crude (5) 3-(10H-phenothiazin-10-yl)propane-1-sulfonyl chloride (9.84 g, 0.029 mol) (filtrate of the preceding step) was added 50 ml dry MeCN under nitrogen flux, and the resulting solution was transferred to the fritted Schlenk funnel. The Schlenk funnel was purged with nitrogen and plugged with a stopper secured with a clip. The solution of MeCN and (5) 3-(10H- phenothiazin-10-yl)propane-1-sulfonyl chloride was added dropwise to the 3-neck flask over a period of one hour at room temperature. The contents of the 3-neck flask were refluxed for 24 hours. Formation of bulky precipitate was observed. The precipitate was filtered off and the resulting solution was concentrated under vacuum. The residue was recrystallized from water to yield the product (7) potassium 3-(10H-phenothiazin-10-yl)propane-1-triflamide, in the form of brown needles.

The contents of the flask were subjected to reflux overnight, followed by cooling to ambient room temperature. The resulting precipitate was collected and washed twice with MeCN to yield 4.96 g of 3,3’-([4,4’-bipyridinium]-1,1’-diyl)bis(propane-1-sulf onate) (15). Scheme-(3) Part-2 Synthesis Example-4 [0182] With reference to Scheme-(4) below, there is provided a non-limiting description of the preparation of a cathodic component according to the present invention represented by Formula (I), where R 1 is N-triflylpropane-1-sulfonamide, R 2 is phenyl, and the counter-anion is bis(trifluoromethane)sulfonimide. To an Erlenmeyer flask equipped with a magnetic stirrer was added 4,4'-bipyridine (13) (20.3 g) and 1-chloro-2,4-dinitrobenzene (20) (15.6 g). Next, acetone was added (100 ml) and a reflux condenser was connected. The reaction mixture was refluxed under stirring for 24 hours. After cooling to room temperature, the mixture was filtered, and greenish solid was washed with hexane 3 times. Drying of the resulting solid with air gave 1-(2,4-dinitrophenyl)-4,4' bipyridinium chloride (22) with 57-67% yield (20.5-24.0 g). [0183] To an Erlenmeyer flask equipped with a magnetic stirrer was added 5 g of (22) and ethanol (100 ml). Next, aniline (24) (3.5 ml) was added under stirring. A reflux condenser was connected and the reaction mixture was refluxed for 2 hours. The mixture was cooled to room temperature and solvent was removed on rotary evaporator. Water (200 ml) was added to the residue and the mixture was stirred at room temperature for 30 min. The mixture was filtered, and the solution was evaporated on rotary evaporator to give a yellow solid. This solid was washed with acetone 3 times and dried with air to give 1-phenyl-4,4'-bipyridinium chloride (26) with 95-99% yield (3.6-3.7 g). [0184] To an Erlenmeyer flask equipped with a magnetic stirrer was added 1-pheny1-4,4- bipyridinium chloride (26) (1g) and acetonitrile (80 ml). Then under stirring, a solution of potassium 3-chloro-N-triflylpropane-1-sulfonamide (28) (1 eq) in acetonitrile (20 ml) was added to the mixture. A reflux condenser was connected and the solution was refluxed under stirring for 4 hours. After cooling to room temperature, the mixture was filtered and the solid was washed with acetonitrile 2 times, then dried with air to give ((3-(1'-phenyl-[4,4'-bipyridin]- 1,1'-diium-1-yl)propyl)sulfonyl)triflamide (30) with 79% yield (1.2 g). [0185] To a glass beaker equipped with a magnetic stirrer was added, 1 g of (30) with water (50 ml). The mixture was stirred until full dissolution of starting reactant, then a solution of lithium bis(trifluoromethane)sulfonimide (32) (1.2 eq) in water (10 ml) was added dropwise under vigorous stirring at room temperature. The mixture was stirred for 30 min, then filtered. The white solid was washed with water 5 times and dried with air to give (34), referred to herein as PhVT, with 77% yield (1.2 g).

[0187] Into a double-neck, 2 liter round bottom flask fitted with a mechanical stirrer, was added 95 g of (11) lithium bis(trifluoromethane)sulfonimide and 300 ml of deionized water The contents of the flask were then stirred at 500 rpm, and heated to and held at 80°C. While maintaining the contents of the flask at 80°C, 250 g of (10) poly(diallydimethylammonium chloride) 20 wt% in water (obtained commercially from Sigma-Aldrich; having a reported Mw of 400 to 500 kDa) was added dropwise (310 mmol of chloride) over a period of 10 minutes. The contents of the flask were vigorously stirred at 800 rpm for 18 hours, followed by cooling to ambient room temperature, which resulted in the formation of a precipitate. The precipitate was collected by vacuum filtration, and washed several times with deionized water. [0188] To a double-neck, 2 liter round bottom flask fitted with a mechanical stirrer, was added the collected and washed precipitate, 500 ml deionized water, and 10 g of (11) lithium bis(trifluoromethane)sulfonimide. With stirring at 800 rpm, the contents of the flask were heated to and held at 80°C for 18 hours, followed by cooling to ambient room temperature, which resulted in the formation of a precipitate. The precipitate was collected by vacuum filtration and washed several times with deionized water, followed by several washings with methanol. The washed precipitate was collected and placed in a cellulose thimble, and Soxhlet extraction was conducted with methanol for 24 hours. The solvent was switched to acetone to collect the desired fraction. The solvent was removed under vacuum, and the resulting powder was dried under vacuum, which resulted in 110.9 g of (12) poly((diallydimethylammonium bis(trifluoromethane)sulfonimide)), at a yield of approximately 88%.

To the initial solution was added 5 g of poly((diallydimethylammonium bis(trifluoromethane)sulfonimide)) (PDADMA-TFSI), and then the combination was subjected to vigorous stirring with heat to form a thick solution. While hot, a volumetrically dosed portion of this solution was drop cast onto a fluorine-doped tin oxide (FTO)-glass electrode (3” x 4”; 7.62 cm x 10.16 cm) that had copper tape wrapped over the edge, which was covered with insulating polyimide. A prefabricated thermoplastic gasket of 0.5” (1.27 cm) in width and 400 microns in thickness was added, which surrounded the active area.
