用相应的卤代芳烃与2-三丁基锡基噻吩在Pd(PPh3)4催化下合成了二噻基苯并噻二唑和二噻基苯两种噻吩类衍生物。在室温条件下,用无水FeCl3作为氧化剂,采用固相合成法制得了相应的共聚物。对所得的聚合物的形貌作了分析,并通过红外光谱、紫外-可见吸收光谱、荧光光谱等对所得聚合物的基本性能进行了表征。结果表明该共聚物在313nm和448nm处出现紫外吸收峰;在508nm处激发,在592nm处出现相应的荧光发射光谱。
Two thiophene derivatives of dithiobenzothiadiazole and dithiobenzene were synthesized by the corresponding halogenated arenes and 2-tributyltinylthiophene under the catalysis of Pd (PPh3) 4. At room temperature, anhydrous FeCl3 was used as oxidant, and the corresponding copolymer was obtained by solid phase synthesis. The morphology of the obtained polymer was analyzed, and the properties of the obtained polymer were characterized by infrared spectroscopy, UV - visible absorption spectroscopy and fluorescence spectroscopy. The results showed that the copolymer appeared UV absorption peak at 313nm and 448nm; excitation at 508nm, the corresponding fluorescence emission spectrum at 592nm.
