卟啉边缘的金属有机四面体形成含有1-4当量富勒烯C-60的主客体络合物，这取决于所用的溶剂。C-60的分子在定义明确的口袋中反协同结合;获得了四面体内三个富勒烯的X射线晶体结构。电化学测量表明，胶囊内的富勒烯的电子接受性能的改变取决于封装的模式。观察到多个富勒烯的结合增加了整个簇的电子亲和力，提供了一种调节富勒烯电子学的非共价方法。
A porphyrin-edged metal organic tetrahedron forms host guest complexes containing 1-4 equiv of fullerene C-60, depending on the solvent employed. The molecules of C-60 were bound anticooperatively within well-defined pockets; an X-ray crystal structure of three fullerenes inside the tetrahedron was obtained. Electrochemical measurements revealed that the electron-accepting properties of the fullerenes inside the capsules were altered depending on the mode of encapsulation. The binding of multiple fullerenes was observed to increase the electron affinity of the overall cluster, providing a noncovalent method of tuning fullerene electronics.
