A sensitized europium complex generated by micromolar concentrations of copper(I): toward the detection of copper(I) in biology.
Formation of a luminescent device by the Huisgen 1,3-dipolar cycloaddition reaction between a Eu(III) complex and dansyl azide is reported. This reaction is catalyzed by a common biological copper(I) complex [GS--Cu(I)], and the resultant copper(I) catalytic sensor shows a 10-fold enhancement of europium luminescence emission.
