| 英文摘要 | The photoinduced electron transfer from excited singlet and triplet states of hypocrellins to three electron accepters, namely, methyl viologen chloride (MV), tetrachloro-p-benzoquinone (TCQ) and 2,3-dichloro-5,6-dicyan-p-benzoquinone (DDQ), has been investigated by fluorescence and time-resolved transient absorption spectra. In acetonitrile solution, DDQ and TCQ quenched the fluorescence and T-T absorption of hypocrellins (HA and HE) efficiently, while neither fluorescence nor T-T absorption of them could be quenched by MV. The quenching resulted from the electron transfer between excited hypocrellins and the electron accepters was controlled by diffusion. The rate constants of electron transfer from excited singlet and triplet of HA to DDQ are 9.20 x 10(10) dm(3) mol(-1) s(-1) and 1.28 x 10(9) dm(3) mol(-1) s(-1), respectively. The transient absorption spectra of the formed radical cations of hypocrellins are reported. |
