Development of efficient fluorosensors for the transition metal ions by tuning of photoinduced intramolecular electron transfer (PIET) communication between the components
4-Methoxy-1,8-naphthalimide derivatives, 1 and 2, with improved PIET interaction, show significant fluorescence enhancement in the presence of transition metal ions.
