One cadmium (II)-based metal−organic framework as high-efficiency multi-functional fluorescence chemosensor targeting for the determination of Fe3+, Cr2O72– and CrO42– in aqueous phase

• Four MOFs were prepared and characterized. • Cd-MOF behaves a multi-functional chemosensor toward Fe 3+ , Cr 2 O 7 2− and CrO 4 2– . • Sensing mechanisms of Cd-MOF are supported by PXRD, ICP-AES, FT-IR spectra, UV−vis or XPS and SEM mapping. • Magnetic and cyclic voltammetry properties of Ι−Ⅲ have been investigated. Four MOFs have been synthesized and characterized. Cd-MOF (Ⅳ) behaves as a multi-responsive fluorescence chemosensor targeting...
