Abstract

An electrochromic solution includes a hydrazone compound as an anodic compound is disclosed. The hydrazone compound has a general formula (I)

wherein R₁, R₂, R₃ and R₄ are individually selected from a group consisting of hydrogen, alkyl containing 5 to 20 carbon atoms, alkenyl containing 2 to 20 carbon atoms, alkynyl containing 2 to 20 carbon atoms, and aryl containing 5 to 20 carbon atoms which are unsubstituted or optionally substituted with one or more ester, ether, aryl, amine, thioester, alkyl, alkoxy, alkene, alkyne, CN, F, Cl, Br, I and/or organometallcene functional group.

Claims

1. A hydrazone compound for use as a component of an electrochromic composition, represented by the formula (II):

wherein

respective aryl rings are individually unsubstituted or optionally substituted with one or more ester, ether, aryl, amine, thioester, alkyl, alkoxy, alkene, alkyne, CN, F, Cl, Br, I and/or organometallcene functional group.
