Abstract:
A chromic liquid capable of responding to and reproducing external optical color illumination is formed as a TiO 2 colloid imbued with three sensitizing dyes. The dyes are (a) SQ2 (5-carboxy-2- [ [3- [ (2, 3-dihydro-l, l-dimethyl-3-ethyl-lH-benzo [e] indol-2- ylidene) methyl] -2-hydroxy-4-oxo-2-cyclobuten-l-ylidene] methyl] -3, 3-dimethyl-l-octyl-3H-indolium), (b) LEG4 (3-{ 6- {4- [bis (2', 4'- dibutyloxybiphenyl-4-yl) amino-] phenyl] -4, 4-dihexyl-cyclopenta- [2, 1-b: 3, 4-b'] dithiophene-2-yl] -2-cyanoacrylic acid) and (c) L0 (4- (diphenylamino) phenylcyanoacrylic acid).
