中文摘要 | a detailed investigation on the adsorption behavior of neutral red (nr) molecules on mercaptoethane sulfonate-monolayer protected gold clusters (mes-mpcs) has been conducted by the spectroscopic method. it is found that cationic nr molecules are adsorbed on the negatively charged mpcs surfaces via electrostatic attractive forces. the absorption study shows that the optical properties of nr molecules are significantly influenced upon the adsorption. based on the electrostatic adsorption nature and the excellent stability of mes-mpcs against the electrolytes, this association can be released by the addition of electrolyte salts, which can be monitored by both absorption and fluorescence spectroscopy. in addition, dication ca2+ is found to be more effective in the release of nr than univalent na+. moreover, the mes-mpcs exert energy transfer quenching of nr fluorescence by both static and dynamic quenching. however, static quenching seems to be the dominating quenching mechanism. furthermore, this energy transfer quenching exhibits strong dependence of au core size, and 5.0 nm mpcs show stronger ability in quenching the nr fluorescence than that of 2.7 nm mpcs. |
