利用紫外光谱、荧光光谱研究了ＰＶＫ／Ｃ_（６０）~＊（Ｃ_（６０）~＊与Ｃ_（７０）混合物）体系的光谱行为，实验结果表明，ＰＶＫ与Ｃ_（６０）之间存在电荷转移络合作用。紫外光谱结果表明ＰＶＫ／Ｃ_（６０）~＊电荷转移络合物的特征吸收峰在４７４ｎｍ附近，这与理论计算结果相吻合．ＰＶＫ单元与Ｃ_（６０）之间的最佳匹配约为５：１．荧光光谱结果进一步证明了ＰＶＫ与Ｃ_（６０）~＊之间的电荷转移络合作用的存在。
The spectra of PVK / C_ (60) ~ * (C_ (60) ~ * and C_ (70)) systems were studied by UV and fluorescence spectroscopy. The experimental results show that there exists charge transfer between PVK and C_ (60) Complexation. UV spectroscopy results show that the characteristic absorption peak of PVK / C_ (60) ~ * charge-transfer complex is around 474nm, which agrees well with the theoretical calculation. The best match between PVK cell and C_ (60) is about 5: 1. Fluorescence spectra further prove the existence of charge transfer complexation between PVK and C_ (60) ~ *.
