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. 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.
