A new mol. fluorescent sensor (L) for Cu2+ was synthesized by derivatizing the lower rim of calix[4]arene with benzothiazole moiety, through amide linkage to result in 1,3-di-derivative The receptor mol., L exhibited fluorescence quenching towards Cu2+ among eleven divalent ions, viz., Mn2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, Hg2+, Ca2+, Mg2+ and Pb2+, studied. The 1:1 stoichiometry of the complex formed between L and Cu2+ was demonstrated by electronic absorption and ESI-MS. The role of calix[4]arene for the selective sensing of Cu2+ was established by comparing the data with that obtained for an appropriate control mol. The min. concentration at which L can detect Cu2+ is 403 ppb. The computations carried out at DFT level provided the coordination and structural features of the Cu2+ complex of L as species of recognition. The Cu2+ complex thus formed recognizes iodide by bringing change in the color, among the 14 anions studied.
