Description Di-amido-derivatives of 1,1'-methylene-bis(2-naphthol) (mbn), viz.; L-1 to L-6 and L-7, have been synthesized and characterized. The single crystal X-ray structure of L-2 has been established. All these derivatives have been studied for metal ion recognition by fluorescence and absorption techniques. Among these, L-6 and L-7 were found to be selective towards Cu2+ even in the presence of other metal ions in aqueous acetonitrile owing to the presence of the N,O-binding core up to the lowest concentration of 210 +/- 11 and 144 +/- 3 ppb, respectively. The binding region has been identified by H-1 NMR studies. The proposed mode of binding has been modelled by DFT computations.
