A mononuclear zinc complex for selective detection of diphosphate via ESIPT fluorescence turn-on†
Abstract
A mononuclear zinc complex has been found to exhibit unexpected selectivity for biologically important diphosphate anions (PPi and ADP). The diphosphate binding could turn-on excited state intramolecular proton transfer (ESIPT), whose study reveals mechanistic insight to aid the future design of new sensors.
