摘　　要：C60 富勒烯与 2 (哌啶 -硫代荒酸酯 ) 1,3 丁二烯通过Diels Alder环加成反应得到C60 富勒烯 -哌啶硫代荒酸酯稠合体 ,运用现代波谱技术等确定了产物结构 ;用半经验方法PM3和AM1计算预测环加成反应性和C60 富勒烯 -哌啶硫代荒酸酯稠合体的性能 .激光光解时间分辨技术初步探究了单加成的C60 富勒烯 -哌啶硫代荒酸酯稠合体 (C60 PX)三线态特征以及与四 ( 2 噻吩基 ) -四硫富瓦烯 (TT TTF)分子间的光诱导电子转移反应 .Synthesis of C-60-fullerene containing piperidinoxanthate dyad by the Diels-Alder reaction of 1,3-butadien-2-yl piperidinoxanthate with C60-fullerene was described. Semi-empirical methods (AM1 and PM3) were carried out to calculate front orbits and the properties of C-60-fullerene containing piperidinoxanthate dyad. Mono- and multi-adducts were confirmed by IR, UV, H-1 NMR, C-13 NMR and FAB-MS. The triplet state properties and photoinduced electron transfer processes between C-60-fullerene-containing piperidinoxanthate dyad and tetrakis(2-thienyl) tetrathiafulvalene have been studied by nanosecond laser flash photolysis.
