Abstract

A variety of liquid crystals with semifluorinated tails including 4-alkoxybenzoic acids (1d–h), 4-alkoxybenzoyl hydrazines (2d–h), and N, N′-bis (4-alkoxybenzoyl) hydrazines (3d–m) have been synthesized, and their properties are compared with their perhydrogenated analogs. Semifluorination in compounds 1d–h suppressed nematic phases, and semifluorinated compounds 2d–h exhibit mesogenic behavior where none is found in ...
