Abstract
A new series of liquid crystalline polysiloxanes with a very wide range of mesomorphic temperatures had been prepared. They contained 4-cholesteryl-(10-undecen-1-yloxy)biphenyl- 4¢-carboxylate mesogenic and 4-biphenyl-4¢-allyloxybenzoate mesogenic side groups displaying an enantiotropic cholesteric phases. The mesomorphic polysiloxane specimen with the widest temperature range was used as the stationary phase in a gas chromatography capillary column and it showed high column efficiency and made great promise for the separation of different structure isomer compounds.
