Ni(II)/Zn(II)-Triazolate Clusters Based MOFs Constructed from a V-Shaped Dicarboxylate Ligand: Magnetic Properties and Phosphate Sensing

Publication date: Available online 12 March 2018 Source:Journal of Solid State Chemistry Author(s): Yong-Qiang Chen, Yuan Tian, Na Li, Sui-Jun Liu Two isomorphous metal-organic frameworks (MOFs) {[M2(μ 3-OH)(trz)(sdba)(H2O)]·3H2O}∞ (M = Ni for 1, Zn for 2, Htrz = 1,2,4-triazole, H2sdba = 4,4ʹ-sulfonyldibenzoate) were obtained under the same reaction condition. Both of complexes present a three dimensional 8-c framework with whc1 topology based on M4-(μ 3-OH) units. Moreover, the magnetic properties of 1 and anion sensing of 2 were investigated. The magnetic study show that the domain antiferromagnetic interactions exist in 1. However, complex 2 can be considered as a promising chemical sensor for detecting PO4 3¯by means of fluorescence enhancement among various anions in aqueous solutions. Graphical abstract
