Title:
CALIXARENE POROUS POLYMER WITH ULTRA-HIGH REMOVAL RATE AND ULTRA-HIGH ADSORPTION CAPACITY AND APPLICATION THEREOF IN SELECTIVE SEPARATION OF DYES
Document Type and Number:
WIPO Patent Application WO/2023/092608
Kind Code:
A1
Abstract:
Disclosed in the present invention are a calixarene porous polymer with a ultra-high removal rate and a ultra-high adsorption capacity and an application thereof in the selective separation of dyes. According to the present invention, octafluoronaphthalene and decafluorobiphenyl are used as cross-linking agents, and two calixarene-based porous polymers, namely, POP-8F and POP-10F, are synthesized by means of a simple and mild reaction without using a catalyst. The two polymers show an extraordinary adsorption capacity and adsorption rate on cationic dyes including Rhodamine B (RhB), Methylene Blue (MB) and Crystal Violet (CV), which exceed those of all previously reported porous adsorbents, including COFs, MOFs, POPs, a biomass adsorbent, activated carbon, etc. More importantly, the calixarene-based POPs can effectively remove cationic dyes by means of simple column filtration, and shows excellent reusability. Because of the characteristics, the POP-8F and the POP-10F become porous adsorption materials which can be used for treating and purifying water pollutants.
