The sensing application of 4-(4-chlorophenyl)-3,4-dihydro-1H-chromeno4,3-dpyrimidine-2,5-dione 4b was examined upon addition of different cations by UV–Vis spectroscopy and exhibited excellent sensitivity towards Hg2+ ions by increasing the absorption. The UV–visible absorption spectral data showed good linearity between the UV–Vis absorption of chemosensor 4b and the concentration of Hg2+ with a detection limit of 3.76 × 10–7 M. Furthermore, the chemosensor 4b exhibited an obvious color change from white to light pink in the presence of Hg2+ in EtOH solution.
