Bai, Feng published the artcileSynthesis of a biphenyl-containing, achiral, V-shaped liquid crystalline polyester, SDS of cas: 50670-76-3, the publication is Polymer Preprints (American Chemical Society, Division of Polymer Chemistry) (1999), 40(2), 878-879, database is CAplus.
A new V-shaped liquid crystalline monomer 1,3-Ph bis[4′-(11-hydroxyundecanyloxy)-4-biphenyl]carboxylate was synthesized from 4′-hydroxy-4-biphenylcarboxylic acid, resorcinol, and 11-bromo-1-undecanol. The polymer was prepared by condensing monomer with isophthalic acid under mild condition using 1,3-dicyclohexylcarbodiimide as condensing reagent in the presence of N,N-dimethylaminopyridinium toluenesulfonate.
