中文摘要：
设计、合成了结构新颖的1，4-二（5’-醛基噻吩基-2’）-2，5-二辛氧基苯，并对其结构进行了表征．应用钯催化剂以三丁基锡噻吩与取代的对-二溴苯（3）反应（Stille偶合）生成取代的苯基噻吩（4），产率达到95．2％．由于目标产物（5）本身具有多芳环共轭体系，其荧光效应相当强烈，在氯仿溶液中紫外-可见吸收（Uv-vis）和荧光发射（PL）的最大波长分别为413nm和477nm，固态荧光发射（PL）波长为504nm．
英文摘要：
Using thienyl stannane and palladium-catalyzed （Stille coupling）, 1,4-di（5＇- carbaldehyde-thiophen-2＇-yl）-2,5-dioctyloxy-benzene was synthesized by four steps, the structure was determined by NMR, IR and elemental analysis. The UV-vis absorption and photoluminescence （PL） properties were measured. The absorption bands correspond to π-π^＊ transition with the peak at 413 nm in chloroform solution, the compound exhibited an emissive peak at 477 nm and 504 nm in chloroform solution and solid state respectively.
