| 英文摘要 | The interactions of the model compound (FL4) or diad (FL-AQ) composed of fluorescein and 2-methyl-anthraquinone and TiO2 colloid have been examined by absorption, fluorescence spectroscopy and fluorescence lifetime. This diad (FL-AQ) or model compound (FL4) is adsorbed on TiO2 colloid, through,the phenolic function of the fluorescein moiety. The apparent association constant (K-app) of FL4/TiO2 obtained from the absorption spectra is ca. 3590 mol(-1) . L. The K-app of FL - AQ/TiO2 is ca. 3060 mol(-1) . L. The degree of association ( a) between TiO2 and FL4 is ca. 0.86. The degree of association (a) between TiO2 and FL-AQ is ca. 0.84. The mechanism of the photoinduced electron injection was also discussed through ESR spectra. |
