Coordination disk-type nano-Saturn complexes. Issue 22 (21st February 2020) - Zhan, Shun-Ze
Abstract : 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. Abstract : The first coordination disk-type nano-Saturn complexes, [Cu10 (Mim)10 ]⊃C60 and [Cu10 (Mim)10 ]⊃C70 (Mim = 2-methylimidazolate), were assembled under one-pot solvothermal conditions. The highest number of 30 C–H⋯π interactions between the [Cu10 (Mim)10 ] disk and the C60 /C70 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 [Cu10 (Mim)10 ] disk.
