Abstract

A liquid crystal polymer was synthesized by AIBN free-radical polymerization from an azobenzene mesogen rod-shaped monomer. The liquid crystal monomer was also synthesized by azo-decoupling reaction and Williamson ether synthesis. The thermal property of the LCP monomer was determined by DSC while the structure was determined by FF-IR. It is possible to further confirmed the structure of the synthesized compound if X-Ray diffraction was done. The presence of the azo linkage in both synthesized compounds showed potential for non-linear optic studies as well as photoswitching experiments concerned with cis-trans isomerization cycles.
