摘要：

采用配体取代法合成了以双二苯基膦戊烷（dpppe）及C60为配体、Pt为中心金属的C60Pt(dpppe)新型富勒烯膦金属配合物。 运用质谱、元素分析、紫外-可见吸收光谱、红外吸收光谱和光电子能谱等测试技术对产物进行了表征,同时采用循环伏安法对目标产物进行氧化还原性能研究。 结果表明，C60与金属Pt配位后还原电位发生负移。 结合电子光谱数据确定了目标产物的能级结构，其最高占有轨道和最低非占轨道能级分别为5.635和3.815 eV。 还考察了目标产物在光化学电池中的光伏效应，测试结果表明,在 BQ/H2Q介质溶液中镀层厚度为 1~2 μm 时,具有较好的光电转换性能,光生电压值最高达358 mV。

Abstract:

A fullerene-phosphine metal complex C60Pt(dpppe) was synthesized by ligand substitution method with bis(diphenylphosphino) pentane and C60 as ligand and platinum as central metal. The product was completely characterized by MS, elemental analysis, UV-Vis, IR and XPS. At the same time, the redox properties of the product were studied by cyclic voltammetry. The results showed that the reduction potential was negatively shifted after C60 coordination with platinum. In addition, the energy level structure of the compound was determined by electronic spectrum, and energies of the highest occupied orbital and the lowest unoccupied orbital were 5.635 eV and 3.815 eV. In the meantime, the photovoltaic effect of the complex was determined in the photochemistry cell. The results showed that the fullerene-phosphine metal complex exhibited high photoelectric conversion property, especially under the conditions of BQ/H2Q redox couples, and a maximum value of 358 mV was obtained for the photovoltage when the film thickness was 1~2 μm.

Key words: fullerene, bis(diphenylphosphino) pentane, matel complexes, photoelectric effection
