摘要：

Oxetanes with different mesogenic and spacer groups were synthesized. Some of the polymers obtained by cationic polymerization with BF3.OEt2 as an initiator showed a smectic liquid crystalline phase. Not only cyano-substituted biphenyl but also fluorine-substituted biphenyl were found to be a good mesogenic group in these liquid crystalline polymers. Synthesis and polymerization of the monomers and thermal behavior of the polymers are reported.
