Selective and sensitive turn-on fluorescent Cu2+ sensors (A, B) based on pyrene dye molecule were synthesized. Binding of those toward various cations  (Ca2+, Na+, Fe2+, Fe3+, Ni2+, Cu2+, Co2+, Cr3+, Pb2+, Zn2+, Cd2+, Hg2+) were examined for fluorescent sensing. High selectivity and sensitivity is observed for Cu2+. The fluorescence life time and the quantum yield measurements were carried out for the free ligand and for the copper ligand complex of A and B to understand the mechanistic details of sensing.
