| 英文摘要 | Interaction of hypocrellin A (HA), a naturally perylenequinonoid, with fullerene C-70 has been studied by UV-vis and fluorescence spectra, and the results show that HA and C-70 can form a supramolecular assembly HA/C-70 with a 2:1 stoichiometry in organic solvents and buffer solution containing poly(vinylpyrrolidone) (PVP). The triplet lifetime of HA and C-70 are reduced due to the formation of supramolecular complex. Electron paramagnetic resonance (EPR) studies suggest that photoinduced electron transfer from N,N,N'N'-tetramethyldiethyleneamine (TMEDA) to the excited HA induces the generation of anion radical of HA(HA(center dot-)), followed by further electron transfer from HA(center dot-) to C-70. HA can mediate the electron transfer from TMEDA to C-70 and significantly enhance the intensity of characteristic Near-IR absorption transition of C-70(center dot-), through efficient electron-transfer processes. Upon visible light irradiation, HA/C-70 exhibits stronger photodamage ability on calf thymus DNA under anaerobic condition than HA and C-70. (C) 2010 Elsevier B.V. All rights reserved. |
