Molecular Engineering of Liquid Crystalline Polymers

Abstract

This chapter reviews the molecular engineering of main chain and side chain liquid crystalline polymers. Several factors influencing the phase transitions of liquid crystalline polymers are critically discussed. These include thermodynamics of phase transitions, isomorphism of liquid crystals, rigidity of rod-like mesogens and chemical heterogeneity of main chain liquid crystalline copolymers. The use of polyetherification and copolyetherification and of living cationic polymerization and copolymerization in the manipulation of phase transitions of liquid crystalline polymers is extensively discussed. This review also discusses several novel architectures such as liquid crystalline dendrimers and cyclic oligomers, liquid crystalline polymers containing crown ethers and polypodants, electron donor-acceptor complexes of discotic liquid crystalline polymers, as well as, self-assemblying supramolecular liquid crystalline polymers.
