Description Di-derivatives of 1,1'-methylene-bis(2-naphthol) (L(1)) possessing ester (L(2)), carboxylic acid (L(3)) or picolyl (L(4)) as end groups of the pendants have been synthesized and characterized. Titration of these derivatives for their recognition towards M(2+) (where M = Mg, Ca, Mn, Fe, Co, Ni, Cu, Zn) were performed by following the fluorescence emission intensities in methanol solution. The picolyl derivative (L(4)) has been found to be well suited for Cu(2+) recognition (
