Abstract:
Two metallofullerene frameworks (MFFs) constructed from a penta‐shell Keplerate cuprofullerene chloride, C 60 @Cu 24 @Cl 44 @Cu 12 @Cl 12 , have been successfully prepared via a C 60 ‐templated symmetry‐driven strategy. The icosahedral cuprofullerene chloride is assembled on a C 60 molecule through [η 2 ‐(C=C)]−Cu I and Cu I −Cl coordination bonds, resulting in the penta‐shell Keplerate with the C 60 core canopied by 24 Cu, 44 Cl, 12 Cu and 12 Cl atoms that fulfill the tic @ rco @ oae @ ico @ ico penta‐shell polyhedral configuration. By sharing the outmost‐shell Cl atoms, the cuprofullerene chlorides are connected into 2D or 3D ( snf net) frameworks. TD‐DFT calculations reveal that the charge transfer from the outmost Cu I and Cl to C 60 core is responsible for their light absorption expansion to near‐infrared region, implying anionic halogenation may be an effective strategy to tune the light absorption properties of metallofullerene materials.
