Fl�ssigkristalline asymmetrische Bisphenyl-4,4?-bibenzyldicarboxylate und Polysiloxane mit Bisphenyl-4,4?-bibenzyldicarboxylat-Bausteinen in den Seitenketten, Synthese und Charakterisierung [1, 2]
摘要:
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.
