Synthetic Cationic Cholesteric Liquid Crystal Polymers

We report the synthesis of six multifunctional cationic cholesteric liquid crystals polyesters functionalized with choline, amine and amide groups, to obtain new chemical formulations involving macromolecular features with new properties added to those of precursor chiral cholesteric polyesters. The...
