通过[60]富勒烯和并五苯衍生物之间的Diels-Alder反应合成了高度可溶的[60]富勒烯-并五苯单加合物2a和2b。2a的单晶X射线衍射分析揭示了一个分子的[60]富勒烯部分和相邻分子的并五苯臂之间的吸引力分子间相互作用，导致在溶液中形成头到尾的二聚体。2a和2b在氯仿中的自缔合行为也通过（HNMR）-H-1和荧光光谱观察到。激发和发射波长都可以通过2a和2b的浓度来调制。
The highly soluble [60]fullerene-pentacene monoadducts 2a and 2b were synthesized by a Diels-Alder reaction between [60]fullerene and pentacene derivatives. The single-crystal X-ray diffraction analysis of 2a revealed an attractive intermolecular interaction between [60]fullerene moiety of one molecule and the pentacene arms of an adjacent molecule, resulting in the formation of head-to-tail dimers in solution. This self-association behavior of 2a and 2b was also observed by (HNMR)-H-1 and fluorescence spectroscopy in chloroform. Both the excitation and emission wavelengths can be modulated via the concentration of 2a and 2b.
