The aryl-amine containing azacrown ether ring and alkyl-chloro boradiazaindacene (Bodipy) were synthesized by Schiff base condensation. The absorption and emission of a novel Schiff base derivative (based on azacrown-Bodipy ) were performed in presence of different cations such as Zn2+, Ga3+, Pb2+, Hg2+, NH4+ Ca2+, Cu2+, Na+, Ni2+, Cd2+ and Cr3+. The complexation property of the Schiff base was studied in dimethylformamide (DMF) by interacting azacrown-ether group and transition metal nitrates-ammonium chloride. The electrochemical behavior of the Schiff base has also been investigated by cyclic voltammetry. All experimental results indicated that the new compound act as a selective ratiometric chemosensor for Hg2+.
