摘要：
Single-molecule fluorescent probe: The formation of the highly fluorescent 4-NHOH form of a 3,4-dinitrophenyl-substituted boron dipyrromethane dye can be used to study interfacial electron transfer on individual TiO2 particles (see picture; B yellow, C gray, F green, H white, O red). Kinetic and image analyses of the resulting fluorescence bursts reveal temporal dynamics of molecular interactions and reactive-site distributions. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
