A spirooxazine derivative 1,3-dihydro-1,3,3-trimethyl-spiro[2-H-indole-2-2′-[2H-1,4] oxazino [2,3-f] [1, 10] phenanthroline] (compound 1) was explored as a sensitive Hg2+ probe. Sensing behavior toward various metal ions including Hg2+, Na+, K+, Ag+, Pb2+, Ni2+, Fe2+, Cu2+, Zn2+, Cd2+, Co2+, Ba2+, Mn2+, Cr3+, Al3+ and Fe3+ was investigated by UV–Vis in acetonitrile solution. Benefiting from the strategy of visual detection, this compound showed preferable selectivity and sensitivity for Hg2+ with a detection limit of 0.68 ppm. In addition, the color of the solution was different, when dropping different concentrations of mercury ions (10−8–10−2 M) into the probe (compound 1). This remarkable color variation (lavender to green) could be observed easily by a naked eye. The approach can not only detect the Hg2+ in acetonitrile solution, but also can detect the Hg2+ in sewage and industrial effluents.
