Abstract

A rationally designed novel liquid crystalline monomer was synthesized in four steps from 4-hydroxybenzaldehyde. The cyanobiphenyloxy moiety served as the mesogen with a hexamethylene construct as the flexible tail. Precursors to the monomer exhibited thermotropic liquid crystalline properties. The mesophase range decreased from 1 to 2 to 3. Optical polarized light microscopic investigations revealed the presence of both smectic C and nematic mesophases for each compound. Liquid crystalline monomer 3 underwent thermal cationic polymerization in solution.
