摘要 以三氯化铁为催化剂,采用氧化偶联聚合法合成具有交联活性的聚3-(2-(甲基丙烯酰氧基)乙基)噻吩(P3MET)。用红外光谱、凝胶液相色谱、等速升温热失重分析、紫外-可见光光谱和循环伏安法表征聚合物的结构、热稳定性能和光电性能。结果表明:聚合物的氯仿溶液在350~573nm处有吸收,最大吸收峰位于410nm,其禁带宽度为2.1eV;聚合物的热分解温度为300~400°C,热稳定性能良好;聚合物的电子亲和势能级为3.52eV,电子离子势能级为5.62eV。 Using FeCl3 as catalyst, crosslinkable poly(3-(2-(methacryloyloxy)ethyl)thiophe) (P3MET) was synthesized by oxidative coupling polymerization. The structure, thermal stability and photovoltaic properties of the polymer were characterized by FT-IR, GPC, TGA, UV-Vis absorption and cyclic volta- mmetry measurements. Results indicate that the polymer with absorption onsets ranging from 350 nm to 573 nm in chloroform solution has an absorption peak at 410 nm and an optical bandgap of about 2.1 eV. The thermal decomposition temperature (Td) in the range of 300--400 ℃ demonstrates a good thermal sta bility. The electron affinities (LUMO level) and the ionization potential (HOMO level) of P3MET are 3.52 eV and 5.62 eV, respectively.
