摘要

Abstract A homologous series of 4-alkyl or alkoxy-4′-bromo or cyanotolanes in which the alkyl group is C4→ C10 and the alkoxy group is C1→ C12, has been prepared. Interphase transitions between solid, mesomorphic and isotropic phases were studied by hot stage microscopy and differential scanning calorimeter. The bromo compounds have a smectic polymorphism. Three pure products of cyano derivatives with the chains C9H19O, ...
