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-Hπ 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.

摘要

首个配位盘状纳米土星配合物，[Cu10(Mim)10]⊃C60 和 [Cu10(Mim)10]⊃C70（Mim = 2 - 甲基咪唑盐），是在一锅法溶剂热条件下组装而成的。[Cu10(Mim)10]盘与C60/C70表面之间多达30个C - Hπ相互作用驱动了纳米土星的形成。计算得到的相互作用能比大多数已报道的盘状纳米土星的相互作用能大得多。两种纳米土星体系都存在不同的光致电荷/能量转移机制来淬灭[Cu10(Mim)10]盘的固有发光。
