naked eye detection of Hg2+ in an acetonitrile solution of 1 shows a greenish fluorescence upon UV light irradiation. The isolated Hg2+ complex of 1, 3, shows a similar UV-Vis and fluorescence spectral output as observed from in situ spectroscopic studies of 1 in the presence of Hg2+. Infra-red (IR) and 1H- NMR studies also reveal the interaction of Hg2+ with the quinoline nitrogen atoms as well as with
