摘要: 可溶性聚噻吩和富勒烯(主要是C60 ) 及其衍生物,是聚合物太阳能电池中被广泛使用的给体和受体材料[1 ~ 3],二者之间的相容性和富勒烯的聚集效应是影响光电转换效率的主要因素[4]。本文中,用Suzuki 偶联法逐步合成噻吩的齐聚物,并通过氮卡宾反应将富勒烯和齐聚噻吩用共价键键接在一起,得到单一分子量分布的齐聚噻吩/C60共聚物,可实现分子水平的相连续结构。另外,通过1H-NMR、MALDI-ToF MS 手段对其结构进行表征,通过循环伏安测试表征噻吩单元和C60在基态并无相互作用,紫外可见吸收光谱表明在300 ~ 500nm 处有一个明显的吸收带。

Abstract: Soluble polythiophene (PT) derivatives and fullerenes (mainly C60) are the donor and acceptor materials respectively well-used in the photosensitive blend layer of the polymer solar cells. Aggregation of the fullerenes and phase separation of the donor and acceptor materials in the blend layer influence the power conversion efficiency (PCE) of the devices. So this paper synthesizes thiophene oligomers step by step through Suzuki coupling reaction and connects the thiophene oligomers with the fullerene acceptor together by covalent bond to solve the phase separation problem. By this way,the copolymer(Th2C60 Th4C60 ) can phase separation in molecular level. The molecular structures were determined by H-NMR and MALDI-Toff techniques. Cyclic voltammetry shows there’s no interaction between thiophene and C60 at ground state.

Key words: thiophene oligomers, C60, solar cell
