Abstract

Abstract : A new Zn(ii ) metal–organic framework having 3D CdSO4 topology synthesized and deployed as a dual channel luminescent sensor for ferric ion and nitroaromatics, and a photocatalyst for the degradation of organic dyes. Abstract : A new Zn(ii ) metal–organic framework, formulated as {[Zn(L)]·2.7 DMF} (1 ), was synthesized using a multidentate ligand 1, 4-bis(triazol-1-yl)terephthalic acid (H2 L). The MOF1 adopts 3D uninodal 4-c CdSO4 topology and behaves as a luminescent chemosensor for highly selective and sensitive detection of Fe 3+ and nitro-aromatics, particularly 2, 4, 6-trinitrophenol (TNP). In addition, the thermal stability, UV/Vis diffuse-reflection spectra and photocatalytic behaviors of1 against organic dyes have also been investigated. The possible mechanism associated with the alleviation in the emission intensity of1 in the presence of nitro-aromatic compounds were addressed by theoretical calculations. In addition, the photocatalytic activity of1 against organic dyes was addressed using density of states (DOS) calculations.
