Title:
REVERSE PHOTOCHROMIC COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/143239
Kind Code:
A1
Abstract:
Conventional reverse photochromic compounds have difficulty in sensing light in a visible light region of 600 nm or more used in medical applications, etc. The present invention addresses the problem of providing a reverse photochromic compound and polymer which are highly sensitive even to light of 600 nm or more. The present invention pertains to a compound or the like represented by general formula (1) (wherein, R1 and R4 each independently represent a hydrogen atom or the like, R2, R3, and R5 each independently represent an alkyl group or the like, R6 represents a group having a polymerizable unsaturated group, a carboxy group, an alkoxycarbonyl group, or the like, R31 and R32 each independently represent an alkoxy group or the like, R33 and R34 each independently represent a hydrogen atom or the like, Y1 represents an oxygen atom or a sulfur atom, An- represents an anion, n1-n3 represent a specific integer, and R1 and R2, R3 and R4, and/or R33 and R34 may form an alkylene group.)
