Benzo-fused BODIPY Derivative as a Fluorescent Chemosensor for Fe³⁺, Cu²⁺, and Al³⁺

抄録

The compound (5-(3,5-dimethyl)pyrrol-2-yl)-3-(4-(dimethylamino)styryl)-1,7-dimethyl benzo-fused BODIPY (BFBODIPY-DMP-DMAS) was synthesized and investigated as a fluorescent chemosensor for metal ions. We explored the metal-ion recognition of BFBODIPY-DMP-DMAS in separate acetonitrile solutions of Mg²⁺, Ca²⁺, Ba²⁺, Fe²⁺, Fe³⁺, Co²⁺, Ni²⁺, Cu²⁺, Ag⁺, Zn²⁺, Cd²⁺, Al³⁺, and Pb²⁺. Mg²⁺, Ca²⁺, Ba²⁺, Fe²⁺, Co²⁺, Ni²⁺, Ag⁺, Zn²⁺, Cd²⁺, and Pb²⁺ did not affect the shape or intensity of the fluorescence spectra of the chemosensor. However, the sensor fluorescence was shifted to shorter wavelengths for Al³⁺ and quenched for Fe³⁺ and Cu²⁺.
