在八乙基卟啉镍（NiOEP）修饰的Au（111）表面上，C60和C70富勒烯形成了1：1的超分子组装层，而富勒烯分子作为第二层吸附在四苯基卟啉镍（NiTPP）的第一层上时发生了置换反应.这一结果表明，C60和C70的超分子组装强烈地受到卟啉底层的影响。结果表明，第一吸附层的稳定性是富勒烯在电极表面的主客体选择性的表面设计的一个重要因素。
Highly stable, supramolecular assembled layers with 1:1 composition of C60 and C70 fullerenes were found to form on nickel(II) octaethylporphyrin (NiOEP)-modified Au(111) surface, whereas the replacement reaction of the first adlayer of nickel(II) tetraphenyl porphyrin (NiTPP) occurred upon adsorption of fullerene molecules as the second layer. This result shows that supramolecular assemblies of C60 and C70 are strongly influenced by the underlying layer of porphyrin. It is demonstrated that the stability of the first adlayer is an important factor in the surface design of host-guest selectivity of fullerenes on electrode surfaces.
