Coordination disk-type nano-Saturn complexes

The first coordination disk-type nano-Saturn complexes, [Cu 10 (Mim) 10 ]⊃C 60 and [Cu 10 (Mim) 10 ]⊃C 70 (Mim = 2-methylimidazolate), were assembled under one-pot solvothermal conditions.

Description
Summary:The first coordination disk-type nano-Saturn complexes, [Cu 10 (Mim) 10 ]⊃C 60 and [Cu 10 (Mim) 10 ]⊃C 70 (Mim = 2-methylimidazolate), were assembled under one-pot solvothermal conditions. The highest number of 30 C-H π interactions between the [Cu 10 (Mim) 10 ] disk and the C 60 /C 70 surfaces drives the formation of the nano-Saturns. The calculated interaction energy is much larger than that of most of the reported disk-type nano-Saturns. Different photoinduced charge/energy transfer mechanisms are present for both nano-Saturn systems to quench the intrinsic luminescence of the [Cu 10 (Mim) 10 ] disk. Two coordination disk-type nano-Saturn complexes were assembled. The highest number of 30 C-H π interactions induces the formation of the nano-Saturns. Different photoinduced charge/energy transfer mechanisms quench the luminescence of the disk.
