Abstract

Official abstract text for this publication.

Provided is an electrochromic compound represented by the following general formula (I) or (II) where R 1 to R 13 are each independently a hydrogen atom, a halogen atom, a monovalent organic group, or a polymerizable functional group, and at least one of the R 1 to the R 13 is a polymerizable functional group.

First claim

Opening claim text (preview).

The invention claimed is: 1. An electrochromic compound represented by the formula (II): where R 1 to R 13 are each independently a hydrogen atom, a halogen atom, a monovalent organic group, or a polymerizable functional group having a carbon-carbon double bond, and at least one of R 3 , R 4 , and R 13 is the polymerizable functional group. 2. The electrochromic compound according to claim 1 , wherein the monovalent organic group is an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heteroaryl group, an alkoxy group, an aryloxy group, or a heteroaryloxy group. 3. The electrochromic compound according to claim 1 , wherein R 3 and R 4 are each a halogen atom, a monovalent organic group, or a polymerizable functional group having a carbon-carbon double bond. 4. The electrochromic compound according to claim 1 , wherein the polymerizable functional group is introduced as a substituent at a terminal of an alkyl group, an aryl group, or an aryl group substituted with an alkyl group. 5. The electrochromic compound according to claim 1 , wherein the polymerizable functional group is an acryloyl group or a methacryloyl group. 6. An electrochromic composition comprising: the electrochromic compound according to claim 1 ; and a polymerizable compound different from the electrochromic compound. 7. An electrochromic compound represented by the formula (I): where R 1 to R 13 are each independently a hydrogen atom, a halogen atom, a monovalent organic group, or a polymerizable functional group having a carbon-carbon double bond, at least one of R 3 , R 4 and R 13 is the polymerizable functional group, and R 3 and R 4 are identical and each a halogen atom, a monovalent organic group, or a polymerizable functional group having a carbon-carbon double bond. 8. The electrochromic compound according to claim 7 , wherein R 3 and R 4 are the polymerizable functional group, and R 13 is a hydrogen atom, a halogen atom, or a monovalent organic group. 9. The electrochromic compound according to claim 7 , wherein R 13 is the polymerizable functional group, and R 1 to R 12 are each independently a hydrogen atom, a halogen atom, or a monovalent organic group. 10. The electrochromic compound according to claim 7 , wherein the monovalent organic group is an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heteroaryl group, an alkoxy group, an aryloxy group, or a heteroaryloxy group. 11. The electrochromic compound according to claim 7 , wherein the polymerizable functional group is introduced as a substituent at a terminal of an alkyl group, an aryl group, or an aryl group substituted with an alkyl group. 12. The electrochromic compound according to claim 7 , wherein the polymerizable functional group is an acryloyl group or a methacryloyl group. 13. An electrochromic composition comprising: the electrochromic compound according to claim 7 ; and a polymerizable compound different from the electrochromic compound.
