报告内容简介：We have succeeded the in situ observation of photochemical reactions on individual nanoobjects of solid catalysts using single-molecule, single-particle fluorescence spectroscopy. The use of high-resolution imaging techniques with suitable fluorogenic probes enables us to determine the location of the catalytically active sites that are related to the structural heterogeneities on the surface of the solid catalyst and the temporal fluctuation of photochemical reactivity. We have succeeded the real-time observation of metastable gold nanoclusters in polymer matrices at the single-cluster level. We would like to encourage researchers to explore the nanoworld in terms of practical applications in many fields such as fundamental physics and chemistry.
