Paper Abstract

Organic materials have great potential for electro-optic devices. Achieving higher unidirectional ordering of chromophores is the main challenge in using organic materials in such devices. The prime reason for this decreased order is due to interchromophore interactions which lead to a decrease in the electro-optic coefficient, r33. A material consisting of a chromophore surrounded by dendrons and possessing an appropriate aspect ratio should facilitate the near Ferro-electric ordering as observed in the discotic liquid crystals. For that purpose, a prototype dendrimeric chromophore has been synthesized and will be used in Mach-Zehnder devices to achieve lower drive voltages.
