摘要
就不同溶剂介质和温度对Ｃ６０与三乙胺（ＴＥＡ）电荷转移配合物（ＣＴＣ）的吸光及发光特性影响进行了考察。通过ＵＶ／Ｖｉｓ光谱及荧光光谱证实了它们的存在并计算了相应的ＫＣＴＣ与ｋｑ．实验表明，不同溶剂介质中，Ｃ６０同ＴＥＡ作用的程度为环己烷≈ＣＣｌ４＞甲苯；猝灭效率为ＣＣｌ４＞环≈甲苯。ＣＣｌ４中，ＴＥＡ对Ｃ６０荧光的猝灭受扩散控制，而甲苯、环己烷中则不受扩散控制。
The investigation on the influence factors of the absorption and luminescence properties of charge transfer complex of fullerene with triethylmine is carried out in different solvent media and temperatures.The existance of CTC is demonstrated by UV/Vis and fluorenscence spectra and corresponding k CTC and k q are determined.The experiments show that the interaction extent between C 60 and TEA is in the order:Cyclohexane≈CCl 4>toluene.In the solvent of CCl 4,the fluorenscence quenching of C 60 by TEA is diffusion controlled,while in toluene and cyclohexane, it is not diffusion controlled.
