Exohedral
cuprofullerenes with 6-, 12-, or 24-nuclearity
were obtained by utilizing fluorocarboxylic/dicarboxylic
acid under solvothermal conditions. The 24-nuclear molecule
presents a C60@Cu24 core–shell structure
with a rhombicuboctahedron Cu24 coated on the C60 core, representing the highest nuclearity in metallofullerene.
The resultant complexes show an efficient absorption of visible light
as opposed to the pristine C60. TD-DFT calculations revealed
the charge transfer from Cu(I) and O atoms to the fullerene moiety
dominates the photophysical process.
