通过三种不同的合成路线合成三种新型C60衍生物,这三种合成路线分别为:偶氮烷烃环加成反应,Bingle-Hirsch反应和Prato反应.由于含有不同的化学结构,三种化合物作为电子受体具有不同的电子亲和力.这三种C60衍生物和[6,6]苯基C61-丁酸甲脂(PCBM)一起被制作成聚合物太阳能电池.它们的太阳能电池性能表现出与它们结构和溶解性能很大的相关性.这为选择哪种结构C60衍生物作为聚合物太阳能电池材料提供了指导.

Three different synthetic routes were used to synthesize different C 60 derivatives: azoalkane cycloaddition, Bingle-Hirsch reaction and Prato reaction. With different chemical structures, these three compounds have different acceptor strengths. These C 60 derivatives together with -phenyl C61-butyric acid methyl ester (PCBM) were used for fabrication of solar cells in blend with poly(2-methoxy-5-(2′-ethylhexoxy)-p-phenylene)(MEH-PPV). It was shown that photovoltaic cell performance varies with acceptor structure and the solubility of the C 60 derivatives in organic solvent. Energy conversion efficiency of one of the synthesized methanofullerene-phenyl C 61-butyric acid butyl ester (PCBB), shows better performance than that of PCBM.
