Exohedral cuprofullerenes with 6-, 12-, or 24-nuclearity were obtained by utilizing fluorocarboxylic/dicarboxylic acid under solvothermal conditions. The 24-nuclear molecule presents a C@Cu core-shell structure with a rhombicuboctahedron Cu coated on the C core, representing the highest nuclearity in metallofullerene. The resultant complexes show an efficient absorption of visible light as opposed to the pristine C. TD-DFT calculations revealed the charge transfer from Cu(I) and O atoms to the fullerene moiety dominates the photophysical process.
通过在溶剂热条件下利用氟代羧酸/二羧酸获得了具有6核、12核或24核的外表面铜富勒烯。24核分子呈现出一种C@Cu核壳结构，在C核上包覆着一个菱形立方八面体Cu，这代表了金属富勒烯中最高的核数。与原始的C相比，所得配合物对可见光有高效吸收。TD-DFT计算表明，从Cu(I)和O原子到富勒烯部分的电荷转移主导了光物理过程。
