Thermotropic Liquid Crystals with Nitrocinnamylidene Unit
Abstract
Highly polarizable organic molecules in an ordered morphology are sought after for their non-linear optical properties. Among the polymeric systems that have received alot of attention are poly(diacetylenes) and poly(methacrylates) with liquid crystalline side chains. Although many poly(diacetylenes) have been studied there is none with the side group in strong interaction with the conjugated polymer chains. We reason that poly(diacetylenes) with strongly polarizable side chains attached directly to the conjugated chains should have very interesting optical properties. Furthermore if the monomers are liquid crystalline poly(diacetylenes) with very high order should be obtainable via polymerization in crystalline and/or liquid crystalline states. For ferroelectrical optical displays, on the other hand, polarizable chiral smectic C liquid crystals are desirable. Our approach to these areas started with the design and synthesis of a polarizable mesogen 3- aryl propylenylidene anilines.
