摘    要:利用紫外-可见吸收光谱、瞬态吸收光谱及X射线衍射等方法研究了苝醌染料竹红菌素镁离子配合物(Mg2+-HA)与富勒烯C60的相互作用. 结果表明, Mg2+-HA与C60在溶液和固体状态下都能够形成稳定的超分子. Mg2+-HA存在条件下, C60能够溶于多种极性溶剂, 在二甲基亚砜(DMSO)中的溶解度能够达到1×10-4 mol·L-1. 作为超分子体系中的光捕获分子, Mg2+-HA能显著地提高C60与N,N-二甲基苯胺(DMA)的光诱导电子转移反应效率, 生成的C60负离子自由基的电子自旋共振光谱(ESR)信号强度比未加入Mg2+-HA时增强了9倍左右.

关 键 词:苝醌  富勒烯C60  光诱导电子转移反应  超分子

Abstract:The magnesiumcomplex of hypocrellinA(Mg2+-HA) (a perylenequinonoid compound) and pristine fullerene C60 was used to construct supramolecular assemblies in solution and in the solid state. The assembly was characterized by UV-Vis, transient absorption spectroscopy, and powder X-ray diffraction (XRD). The solubility of C60 in polar solvent improves significantly in the presence of Mg2+-HA. The solubility of C60 in dimethyl sulfoxide (DMSO) is 1×10-4 mol·L-1 when C60 is allowed to complex with Mg2+-HA(4×10-4 mol·L-1). Acting as an antenna molecule in the supramolecular system, Mg2+-HA remarkably enhances the photoinduced electron transfer efficiency between C60 and an electron donor, N,N-dimethylaniline (DMA). The electron spin resonance (ESR) signal intensity of C6-0·increases 9-fold as strong as that in the absence of Mg2+-HA.
Keywords:Perylenequinonoid  Fullerene C60  Photoinduced electron transfer  Supramolecule
