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 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.
Claims7
An electrochromic device for use in a mirror for performing color change of the mirror in response to a voltage applied thereto, comprising:
- a first transparent substrate;
- a second transparent substrate positioned substantially parallel to said first transparent substrate, and spaced apart from said first transparent substrate by a predetermined clearance to form a space therebetween;
- an electrochromic composition including a hydrazone compound, disposed in said space between said first and second transparent substrates;
- a seal disposed between said first and second transparent substrates for retaining said electrochromic composition in said space;
- and
- a pair of transparent electrodes provided on opposite surfaces of said first and second transparent substrates facing said space for providing said voltage for said electrochromic composition to perform color change
