A new Zn(II) metal-organic framework having 3D CdSO4 topology as luminescent sensor and photocatalyst for degradation of organic dyes

Abstract

A new Zn(II) metal–organic framework, formulated as {[Zn(L)]·2.7DMF} (1), has been synthesized using a multidentate ligand 1,4-bis(triazol-1-yl)terephtralic acid (H2L). The MOF 1 adopts 3D uninodal 4-c CdSO4 topology and behaves as a luminescent chemosensor for highly selective and sensitive detection of Fe3+ and nitro-aromatics especially 2,4,6-trinitrophenol (TNP). Additionally, the thermal stability, UV/Vis diffuse-reflection spectra and photocatalytic behaviors of 1 against organic dyes have also been investigated. The possible mechanism associated with the alleviation in emission intensity of 1 in presence of nitro-aromatic compounds have been addressed by theoretical calculations and the photocatalytic activity of 1 against organic dyes have been addressed using density of states (DOS) calculations.
