二噻基苯和二噻基苯并噻二唑共聚物的固相合成

The solid-state phase reaction synthesis of copolymer with dithiophenyl-benzene and dithiophenyl-benzothiadiazole

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 dithiophenyl-benzothiadiazole and dithiophenyl-benzene, have been synthesized with relative aromatic halides and 2- （tributylstannyl）thiophene reagent ,using Pd （PPh3）4 as catalyst. In the condition of room temperature, the corresponding copolymer has been prepared with solid-state synthesis method, using FeCI3 as the oxidant. We analyzed its shape .Its structure has been examined by FT-IR, Uv-vis, Fluorescence spectroscopy and so on. The results show that the co-polymer has ultraviolet absorbent peaks at 313 nm and 448 nm, and the eopolymer which was excitated by 508nm wavelength give an emission spectrum with wavelength at 592nm.
