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.

1,3-Dipolar cycloaddition of DTE-azomethine ylides (DTE: dithienyl-ethene) to C60 in refluxed toluene was used to synthesize novel dumbbell-type fullerene dimer 1. For the sake of comparison, the monoadduct 2 were also synthesized. The molecular geometries of these two compounds were determined by theoretical calculations with HF-3/21G method. UV-Vis and fluorescence experiments were carried out in solvents with different polarity at the room temperature. All the results indicated the existence of a photoinduced intramolecular electron transfer process between the donor and acceptor moieties.
