Title:
DITHIENOPHOSPHORINE COMPOUND, AND COLORLESS NEAR-INFRARED ABSORBING MATERIAL AND ELECTROCHROMIC MATERIAL EACH USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/176755
Kind Code:
A1
Abstract:
This dithienophosphorine compound having a cation represented by the formula (wherein Y represents an oxygen atom or a sulfur atom; R1 represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heteroaryl group; R2 represents a hydroxy group, an alkyl group, an alkoxy group, an alkenyl group, an alkynyl group, an aryl group or a heteroaryl group; each of R3, R4, R5 and R6 represents a hydrogen atom, an alkyl group, an alkenyl group or an aryl group; each of R7 and R8 represents an arylene group and/or a heteroarylene group; each of R9 and R10 represents a hydrogen atom, a halogen atom, a sulfonyl group, an alkyl group or an aryl group; each group may have a substituent; and R3, R4 and R7, and R5, R6 and R8 may combine with each other to form a ring together with an adjacent nitrogen atom) is an organic compound which has a maximum absorption wavelength in an NIR-II range (from 1,000 to 1,500 nm) although the molecular weight thereof is not extremely high, and which exhibits excellent solubility in an organic solvent, while having high structural selectivity.
