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.
