Abstract

The complexes [EuL¹]³⁺ and [EuL²] function as luminescent pH sensors over an extended pH range; two distinguishable pH switching ranges are observed: the delayed europium emission is switched on in acidic solution, whereas the fluorescence emission spectra show a pronounced pH dependence only in alkaline media.
