Original Paper


An efficient colorimetric sensor with pyrrole-NH moiety as binding site and nitro group as a signaling unit has been synthesized by a one step procedure and characterized by spectroscopic techniques, which displays excellent selectivity and sensitivity for fluoride and hydroxide ions. The hydrogen bonding with these anions provides remarkable colorimetric responses. 1H NMR and FT IR studies has been carried out to confirm the hydrogen bonding. UV–vis and fluorescence spectral changes can be exploited for real time and on site application.
