  Aim: The chemosensors permitting naked eye detection of toxic metal ions are user-friendly, portable and obviate the requirement of sophisticated equipments. The objective of the present study was to develop a PET (photoinduced electron transfer) based chemosensor for Zn2+ that changes its color upon binding to Zn2+ allowing naked eye detection. Methods: A new 4-piperazino-1,8-naphthalimide based fluorescent probe 1 was synthesized and its structure was determined using NMR and XRD techniques. The solvatochromic effects on the absorbance and fluorescence characteristics of 1 in aqueous and non-aqueous media were explored. Metal ion competition experiements were performed to monitor the interference of common ions like Li+, Na+, K+, Cu2+, Mg2+, Ca2+, Cr3+, Mn2+, Fe2+, Co2+, Ni2+, Zn2+, Cd2+, Hg2+ and Pb2+.
