Strong emission increase of a dicarboxyterpyridene europium (III) complex in the presence of citrate and hydrogen peroxide

A substituted 6,6″-dicarboxy-2,2′:6′,2″-terpyridene europium (III) complex (1) responds with an emission wavelength shift and intensity increase to the presence of citrate and hydrogen peroxide, while many oxoanions show no effect.

Europium (III) complex 1 responds in aqueous buffered solution to the presence of citrate with changes of emission intensity and wavelength.Figure optionsDownload as PowerPoint slide
