A series of mesogen-jacketed liquid crystalline polymers, poly{2,5-bis[(4-alkoxyphenyl)aminocarbonyl]styrene} (P-Cm, where m is the number of carbon atoms in the alkoxy groups, and m = 1, 4, 8, 12), with an amide core and flexible tails of varying lengths on the two ends in the side chain were designed and successfully synthesized via conventional radical polymerization. The mesophase structures of these polymers were dependent on the number of carbon atoms in the peripheral chains. Wide-angle X-ray diffraction and polarized light microscopy results revealed that the polymers with m ≥ 4 could form smectic A phases, while a columnar nematic phase could be formed for the polymer with methoxy end groups (P-C1). The hydrogen bonding among the side-chain amide groups might play an important role in forming and stabilizing these liquid crystalline phases, which was suggested by the results from variable-temperature FTIR and 2D IR analyses.

A dendritic cyclotriphosphazene derivative was synthesized by substitution with six alkylazobenzenes onto cyclotriphosphazene. Photo-induced trans-to-cis isomerization of the azobenzene moieties was discussed on each substituent. It was also investigated
Effect of Molecular Structure on Mesomorphism. 22. Liquid Crystalline 1-Alkanol Derivatives

Several 1-alkanols having a mesogenic unit attached to the omega-carbon have been prepared.Many of these are liquid crystalline.The nematic mesophase is predominant for these materials.This is presumably due to intermolecular hydrogen-bonding between polar terminal groups such as cyano or nitro and the primary hydroxyl functionality of a proximal molecule.The resulting end-to-end association favors a nematic mesophase.
