The present invention provides fluorogenic compounds for the detection of target metal ions wherein the compounds exhibit a Stokes shift greater than 50 nm and the detectable signal is modulated by photoinduced electron transfer (PET). The present compounds consist of three functional elements, the ion sensing moiety (chelating moiety), the reporter moiety (fluorophore or fluorescent protein) and spacer or linker between the sensing and reporter moieties of the present compound that allows for PET upon binding of a metal ion and excitation by an appropriate wavelength.
