Abstract

Abstract : A novel luminescent Cd-MOF based on trinuclear Cd cluster and H2 PZC ligand has been constructed, it may be used as a potential luminescent probe for the detection of acetone, Na + and Fe 2+ . Abstract : A novel three-dimensional metal–organic framework (MOF), [H3 O][Cd3 Cl(PZC)3 (H2 O)3 ] (1 ), has been synthesized based on a trinuclear Cd(ii ) cluster and H2 PZC ligand (H2 PZC = 1 H -pyrazole-4-carboxylic acid). Compound1 crystallizes in a trigonal crystal system with the space group R 3 m . Trinuclear Cd(ii )-clusters as secondary building units (SBU) are further connected by the H2 PZC ligand to form a two-fold interpenetrated 3D framework. Compound1 exhibits excellent water-stability and good luminescence properties for various organic solvents and different metal ions. The systematic investigation for luminescence indicates that compound1 possesses unique performance for the detection of acetone, Fe 2+ and Na + based on a fluorescence quenching and enhancing mechanism, thus it can be regarded as a potential luminescence probe for the detection of acetone, Fe 2+ and Na + .
