A new series of liquid crystalline polysiloxanes with a very wide range of mesomorphic temperatures has been prepared. They contain 4-cholesteryl-(10- undecen-1-yloxy) biphenyl-4'-carboxylate mesogenic and 4-biphenyl-4'- allyloxybenzoate mesogenic side groups displaying enantiotropic nematic and chiral nematic 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 unique separation properties for polycyclic aromatic compounds.
