SYNTHESIS OF A GROUP OF MESOGEN JACKETED LIQUID CRYSTAL POLYMERS
摘要:
A group of the mesogen jacketed liquid crystal polymers based on the monomers 2,5-bis (4-substituted benzoyl)oxystyrenes are synthesized. The substituents include alkoxy, alkyl, and cyano groups. The synthesis and the primary characterization of the liquid crystal phase of the monomers and the polymers are described. While some of the monomers give smectic textures the polymers are found to be nematic above their melting or glass transition temperatures. Interestingly the unsubstituted monomer and its polymer poly 2,5-di(benzoyloxy) styrene are also liquid crystalline.The single crystal structure of one of the monomers is also discussed.
