A new naphthoquinone-based chemosensor 2HPN for the selective detection of Fe2+ ion has been developed. The sensing property of the chemosensor 2HPN was evaluated in aqueous acetonitrile (CH3CN) medium by a fluorescence emission method. The metal binding studies of ligand 2HPN showed selective “turn-on” fluorescence responses for Fe2+ ion (Ka = 1.0 × 106 M-1). The detection limit of the ligand 2HPN to Fe2+ was calculated to be 0.272 µM, which is lower than the World Health Organization (WHO) recommendation (0.3 mg/L) in drinking water. The most significant feature for the obtained chemosensor 2HPN it the ability to sense Fe2+ via naked-eye detection over various metal ions. The chemosensor operated through the intramolecular charge transfer (ICT) mechanism that was further supported by FT-IR analysis, NMR titrations, and DFT calculations. The efficiency of the chemosensor 2HPN as a biomarker for Fe2+ was successfully demonstrated by bio-imaging of human cancer cells and zebrafish.
