Synthesis, Optical and X-ray diffraction study of transition metal complex of Cu (II) containing napthaquinone dibenzo 18- crown-6

The trans- (dinitrobenzo)-18-crown-6 to trans –di (aminobenzo)-18 crown –6 was reduced to trans-di- (aminobenzo)-18 crown –6 and subsequently condensed with the 1,4-napthaquinone to give the target molecule (4b) (Scheme I). The synthesized compounds have showed the chromogenic ionophoric properties examined by UV-Visible absorption of the host in DMF. The DMF solvent was found to be an efficient and selective for chromogenic responses for different alkali and transition metals like Ca, Sr, Ba, Ni and Cu. among these Ni (II) and Cu (II) showed excellent results. In addition to this, we have reported the X-ray diffraction study of Cu (II) complexes
