Abstract

Two isomorphic 3D MOFs [Cd(2-bpeb)(sdba)] (1) and [Zn(2-bpeb)(sdba)] derived from the π-conjugated pro-ligand 2-(4-((E)-2-(pyridine-2-yl)vinyl)styryl)pyridine (2-bpeb) and 4,4’-sulfonyldibenzoate (H2sdba) were synthesized and characterized. Complexes 1 and 2 exhibit striking fluorescence properties and can function as chemical sensors via rapid luminescence quenching in the presence of Fe3+and Cr2O72- in aqueous media with high sensitivity and selectivity.
