摘　　要：以碘代烷氧基苯与烷基苯乙炔为中间体,采用为催化剂偶联的方法合成了二苯乙炔类液晶化合物。通过对这类液晶化合物的相变研究,证实这类液晶化合物具有优良的液晶性能。A series of tolan-type liquid crystals were synthesized using catalyst. Their phase transition temperature was also measured by texture observation with an optical polarization microscopy and confirmed by different scanning calorimetry. All compounds exhibit excellent quality .
