摘要
用GRIM(Grignard Metathesis Method)合成了聚(3-溴己基噻吩),并在硫代乙酸钾和氢化铝锂的作用下合成了巯基化的P3HT衍生物聚(3-(6-巯基己基)噻吩)。通过红外光谱、核磁共振波谱、凝胶渗透色谱、紫外-可见光谱、荧光光谱以及电化学分析对中间产物和最终产物的结构和光电性能进行了表征。结果表明,所合成聚合物与目标产物的结构一致,聚合物的数均相对分子质量为5621,多分散系数为1.39,在氯仿溶液中最大吸收波长为408 nm,最大发射波长为545 nm,电化学能隙为1.81 eV。
Poly (3-hexyhhiol thiophene) was successfully synthesized using potassium thiolacetate, lithium aluminium hydride and poly (3-bromohexylthiophene) via the GRIM (Grignard metathesis method) method. The structures of intermediates and polymer were characterized by FT-IR, 1H-NMR, GPC, UV-Vis, photoluminescence fluorescence spectrum (PL) and cyclic voltammetry. The results show that the structure of polymer is consistent with goal products. The number average molecular weight of polymer is 5621, and the polydispersity is 1.39. The maximum absorption spectrum wavelength of UV-Vis. is 408 nm and the maximum emission spectrum wavelength of PL is 545 mn in the solution of chloroform, and the cyclic voltammetry shows that the energy band gap is 1.81 eV.
