Abstract:

The encapsulations of fullerenes by carbon-nanorings are of great interest because of their unique molecular structure and special properties. The host-guest interaction between them can induce the orientation of metal ions and change the molecular electronic structure. However, due to experimental di?culties, there are many opportunities for the computational efforts to deeply research the intrinsic features of π-π noncovalent interactions of the fullerene?cycloparaphenylene(CPP) carbon-nanoring host-guest systems. Herein, the molecular carbon nanoring of [12]cycloparaphenylene was used to hoop the C80-based metallofullerene Sc3C2@C80. The structures and properties of the host-guest complex were systematically characterized by density functional theory(DFT) calculations. It was found that [12]CPP is deformed because of the asymmetrical attraction of [12]CPP to Sc3C2@C80. The centroids of Sc3C2@C80 and [12]CPP no longer coincide. The results also showed that the influence of rotation of Sc3C2@C80 in [12]CPP on the overall energy of the configuration is only 13.51 kJ/mol. Moreover, charge population analysis shows that 0.03 electrons are transferred from [12]CPP to Sc3C2@C80 during the formation of Sc3C2@C80?[12]CPP. Weak interactions between host-guest systems can be further partitioned with the help of energy decomposition analysis(EDA). EDA analysis shows that dispersion is dominant. These results provide theoretical support for the study of host-guest systems based on metallofullerenes.
