Abstract
An electrochromic compound represented by Formula (1), wherein R1 is an alkyl group, an alkenyl group, an aryl group, or a heterocyclic group; R2 and R3 are each a hydrogen atom or a substituent; X is N—R4, an oxygen atom, or a sulfur atom; and R4 is a hydrogen atom or a substituent; provided that at least one of R1-R4 has a partial structure represented by Formula (2), —Si(Y)nR′(3-n) Formula (2) wherein Y is a halogen atom or OR, R is an alkyl group, or an aryl group; R′ is an alkyl group, an alkenyl group, an aryl group, or a heterocyclic group, and n is an integer of 1-3.
