Liquid Crystalline Asymmetric Bisphenyl-4,4'-bibenzyldicarboxylates and Polysiloxanes with Bisphenyl-4,4'-bibenzyldicarboxylat Components in the Side Chains, Synthesis and Characterization

Article abstract of DOI:10.1002/prac.19953370129

Asymmetric bisphenyl bibenzyl-4,4'-dicarboxylates with an alkenyloxy- or the 10-undecenoylgroup in the p-position of one terminal benzene ring and the butyl-, an alkoxy- or the thiomethylgroup in the p-position of the other terminal benzene ring (12-14) are synthesized.The olefins 12-14 are added to a poly(methylhydrogensiloxane) 15 to give mesomorphic side chain polysiloxanes 16-18.Data of liquid crystalline properties of 12-14, 16-18 and precursors are discussed.
