A novel rhodamine derivative (Rh-C), synthesized by the reaction of rhodamine ethylenediamine and cinnamoyl chloride, was evaluated as a chemoselective Hg2+ ion sensor. Addition of Hg2+ to an ethanol aqueous solution of the Rh-C resu

A colorimetric and fluorescent indicator based on cinnamamide group-containing rhodamine derivative was synthesized for the detection of Hg2+. The rhodamine B and cinnamamide were connected via ethylenediamine as a bridging molecule through a condensation reaction to obtain a colorimetric and fluorescent indicator for the detection of Hg2+ in H2O-EtOH (4:1, v/v). The indicator was excellent in the selectivity of Hg2+ and was almost unaffected by other common ions such as Na+, K+, Mg2+, Fe3+, Cu2+, Zn2+, Cr3+. The Hg2+-containing aqueous solution turned from colorless to red within 7?min after the addition of the indicator, and had an absorption peak at 564?nm in UV-vis, which implies a significant colorimetric phenomenon. Their characteristic peaks varied with the Hg2+ content, and they reached a linear relationship at low concentrations. The binding stoichiometry proved to be 1:1. The lowest detection limit was 4.1 × 10?7?mol/L, ranging from acidic to neutral.
