A potential fluorescent zinc(II) sensor was synthesized and its spectral profile was studied in aqueous solutions of increasing zinc(II) concentrations. Due to the inherent properties of its chromophore, the sensor exhibits a “turn on” response in solutions of nanomolar zinc(II) concentrations that turns to ratiometric, as zinc(II) ion concentrations reach micro/millimolar levels.
