英文摘要	In this work, an electrochemiluminescence (ecl) reagent bis(2,2'-bipyridine)(5,6-epoxy-5,6-dihydro-[1,10]phenanthroline)ruthenium complex (ru-1) was synthesized, and its electrochemical and ecl properties were characterized. the synthesis of ru-1 was confirmed by ir spectra, element analysis, and h-1 nmr spectra. for further study, its uv-vis absorption and fluorescence emission spectra were investigated. ru-1 also exhibited quasi-reversible ru-ii/ru-iii redox waves in acetonitrile solution. the aqueous ecl behaviors of ru-1 were also studied in the absence and in the presence of tripropylamine. the complex was fabricated on a gamma-(aminopropyl) triethoxysilane (aptes) pretreated indium tin oxide (ito) substrate via aminolysis reaction between the 5,6-epoxy-5,6-dihydro-[1,10]phenanthroline ligand and aptes. the resulting ru-1 modified ito substrate exhibited a broad absorption band in the visible region (350-600 nm) and its fluorescence emission spectrum was centered at 622 nm. the ru-1 modified m electrode showed relative low ecl response. to improve the solid-state ecl response, a gold nanoparticles (gnp)/ru-1 modified ito electrode was constructed. the mixing of gnp and ru-1 could produce the aggregates, which were further immobilized onto a 3-mercaptopropyltrimedioxy-silane (3-mptms) pretreated ito substrate via au-s interactions to construct the gnp/ru-1 modified electrode.
