Patent ID: 8080683

Claim:
An electrochromic compound represented by the following General Formula (1): A-(CX 2 ) n —B General Formula (1) wherein A is a monovalent binding group, B is a redox chromophore, X is a halogen atom, and n is an integer of 1 or more, wherein the redox chromophore B comprises any one of structures represented by the following General Formulas (2a) to (4b): wherein Z 1 to Z 16 are the same or different and each represent a hydrogen atom or a monovalent substituent, R 1 , R 3 and R 5 are the same or different, and each represent a divalent organic group, R 2 , R 4 and R 6 are the same or different, and each represent a monovalent organic group which is represented by General Formula (2a), (3a) or (4a) or divalent organic group which is represented by General Formula (2b), (3b) or (4b), General Formulas (2a), (3a) and (4a) correspond to a case where the redox chromophore B is a terminal group, and General Formulas (2b), (3b) and (4b) correspond to a case where the redox chromophore B is a divalent intermediate group which is interposed between the group —(CX 2 )— and the terminal group, and Y 1 and Y 2 each represent an oxygen atom or a nitride.
