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.
