Azobenzene sulphonic dye photoalignment as a means to fabricate liquid crystalline conjugated polymer chain‐orientation‐based optical structures

Abstract:

The use of a noncontact photoalignment method to fabricate in‐plane optical structures, defined by the local uniaxial ordering of liquid crystalline conjugated polymer chains, is reported. Molecular orientation is demonstrated for both green‐light‐emitting fluorene‐benzothiadiazole alternating copolymer F8BT and F8BT/red light emitting complex copolymer Red‐F binary blend films deposited on a well‐known azobenzene sulphonic dye photoalignment material SD1. Absorption anisotropy ratios of up t...
