Influence of the alkyloxy chains length on the liquid crystalline polymorphism of the 4-alkoxybenzylidene-4'-alkoxyanilines

摘要

The dependence of the temperature of melting and clearing on the alkoxy chains length for 4-alkoxy benzylidene-4'-alkoxyanilines is presented. Conditions at which nematic and smectic C phases are stable are discussed and the entropy effect of clearing is shown.
