摘　　要：以噻吩乙醇为端基,再与对羟基苯甲酸制得的十一烯酰氧基苯甲酸在DCC/DMAP高效酯化条件下得到目标产物,通过核磁、偏光显微镜(POM)对该产物的结构及性能进行了表征。该产物通过一个酯基键把噻吩环和苯环连在一起,形成刚性环的离域化的共扼大π键,加之以十一烯酸的柔性链作为尾链,即柔性链,达到了液晶分子典型的刚柔并济条件,在偏光显微镜检测下呈现较为规整的近晶B7相。Taking thiophene ethanol as end groups, and p - hydroxy benzoic acid of 11 olefine acid acyl oxygen radicals in the DCC/DMAP got the target under the condition of highly efficient etherification product, through nuclear magnetic, polarizing microscope （POM） on structure and properties of the product were characterized. The product through an ester base key ties the thiophene ring and benzene ring, the formation of rigid ring from the domain of the conjugate big ~ bond, along with undecylenic acid flexible chain as the tail chain, namely flexible chain, reached the liquid crystal molecules were typical rigid -flexible economic conditions, presented a more structured under polarizing microscope detection nearly B7 crystal phase.
