Abstract

“C) is reported. The liquid crystals were synthesized by the condensation of the appropriate 4'-alkoxybiphenyl-4-carboxaldehyde with a, a'-bi-p-toluidine. The aldehydes were prepared by a five-step procedure starting with Mydroxybiphenyl. BABT was chromatographically evaluated. BABT operating in the supercooled nematic region at 230 OC provided better separations of methyibenzanthracene Isomers than conventional SE-30, Dexsii 300, and ...
