DTE-甲亚胺叶立德盐(DTE:二噻吩乙烯基)与C60在甲苯中的1,3-偶极环加成反应被用于合成新型的哑铃型富勒烯化合物1．为了与1作比较,还同时合成了单加成物2.并通过HF-3/21G方法计算确定了这两种化合物分子的几何结构,同时在室温下测定了化合物在不同极性溶剂中的紫外-可见光谱和荧光光谱,证明了化合物内给体和受体间光诱导分子内电子转移过程的存在．
The 1,3-dipolar cycloaddition reaction of DTE-azomethine ylide (DTE: dithienylvinyl) with C60 in toluene was used to synthesize a novel dumbbell-type fullerene compound 1. In order to be compared with 1, a single adduct 2 was also synthesized at the same time. The geometrical structures of the two compounds were determined by the HF-3 / 21G method. Meanwhile, the compounds were determined at room temperature in different polar solvents UV-Vis and fluorescence spectra demonstrate the existence of light-induced intramolecular electron transfer between donor and acceptor in the compound.
