中文摘要：

通过Sszuki偶联和Mitsunobu酯化等反应,设计合成了一种新型含氰基三联苯聚噻吩类液晶共轭聚合物单体,利用核磁共振（^1HNMR）、红外光谱（IR）等方法表征了单体的结构。利用示差扫描量热仪（DSC）、带热台的偏光显微镜（POM）、紫外光谱（UV）和荧光光谱（PL）研究了单体液晶性和光电性能。结果表明,该单体具有近晶A型液晶态扇形织构,同时,由于三联苯的存在赋予了单体很好的紫外吸收和光致发光性能,在320nm紫外光激发下,可发射400nm的蓝光。

英文摘要：

A novel liquid crystalline conjugated polythiophene monomer containing cyanoterphenyl via Suzuki reation and Mitsunobu esterification reactions, in sequence. The structure and properties of the monomer were characterized and evaluated with nuclear magnetic resonance （^1H NMR）, infrared spectroscopy （IR）, differential scanning calorimetry （ DSC）, polarized optical microscopy （ POM）, ultraviolet spectroscopy （UV） and photoluminescence （PL）. The monomer exhibits enantiotropic smectic A phases in the heating and cooling processes. The existence of the chromophorie terphenyl core endows the monomer with high photoluminescence, when its solution is photoexcited with 320 nm, the monomer emits a strong blue light about 400 nm.
