The geometry conformation indicates that C 60 has been half-packed by the curved TTF (tetrathiafulvalene) derivatives. Their electronic structures point out that they belong to D-A systems.

• 计算结果显示 ；富勒烯C60 硫桥键联四硫富瓦烯衍生物的四硫富瓦烯 (TTF)平面与C60 发生作用 ；使其弯曲的程度比富勒烯C60 键联四硫富瓦烯衍生物的大 ；从而形成一种独特的四硫富瓦烯 (TTF)平面半包裹C60 的空间构型的D A体系 .
