摘要

Abstract Starting from the pentafluorophenyl ester of 4-(dimethylamino) benzoic acid, two dual fluorescent amide ligands with aza-15-crown-5 and 2-(aminomethyl) pyridine were obtained for sensing, respectively, alkali (alkaline-earth) and transition (heavy) metal cations. The crystal structure of the copper (II) complex is reported. The Cu 2+ is coordinated through the pyridine N-and amide O-atoms of two symmetry-related ligands. The ...
