摘　　要：合成了４个系列共２０个手性双烷氧基端基２－苯基嘧啶化合物，其中１３个是新化合物。液晶性质测试结果表明它们都是近晶相液晶，有些还有多相性。文中讨论了不同端基对液晶性质的影响。Four series ⅠⅣ,total 20 compounds of chiral 2phenylpyrimidine with two alkyloxy terminal groups were synthesized. Among them,13 compounds were new compounds. The chemical structures of all compounds were determined by IR,1HNMR, MS and elementary analysis. Their liquid crystal properties were tested by POM and DSC. The results showed that they all had a smectic phase and some of them had a chiral smectic C phase (Sc*) near room temperature. The effect of different terminal groups on the mesomorphic properties was discussed.
