Abstract
Chiral side-chain liquid crystal polymer is synthesized from polysiloxanes and liqud crystal monomer 4-(Undecenoic-1- yloxybenzoyloxy)-4’-benzonitrile and 6-[4-(4- Undecenoic -1-yloxybenzoyloxy)- hydroxyphenyl] cholesteryl hexanedioate. The optical and thermal property of the monomer and polymer are shown by POM and DSC. As the unique optical property of the polymer, the bandgaps are shifted for heating temperature. The reflection bandgaps is shifted from 546nm to 429nm with temperature increase. As a photonic material, the chiral polymer which sensitive responses under the outfield is widely studied for reflection display, smart switchable reflective windows and defect model CLC laser etc.
