A copper(II)-based metal-organic framework: electrochemical sensing of Cd(II) and Pb(II) and adsorption of organic dyes.

A new inorganic-organic hybrid complex, namely [CuL(DMF)]·HO (Cu-L), has been synthesized using a sulfur-rich ligand, 3,3',3''-(1,3,5-triazine-2,4,6-triyltrisulfanediyl)tripropanoic acid (HL) and metal cations under hydrothermal conditions. The metal atoms are interconnected to form a paddle-wheel-like structure, which is ultimately linked to the ligands to create a three-dimensional architecture. Cu-L, employed to fabricate an electrochemical sensor denoted as Cu-L@GCE (glassy carbon electrode), is capable of simultaneously detecting Cd and Pb at approximately -0.

Sulfur-Bridged Co(II)-Thiacalix[4]arene Metal-Organic Framework as an Electrochemical Sensor for the Determination of Toxic Heavy Metals.

A novel sulfur-bridged metal-organic framework (MOF) · based on thiacalix[4]arene derivatives was successfully obtained using a solvothermal method. Remarkably, adjacent ligands were linked via Co(II) cations to form a three-dimensional (3D) microporous architecture. Subsequently, was modified on a glassy carbon electrode () to produce an electrochemical sensor for the detection of heavy-metal ions (HMIs), namely, Cd, Pb, Cu, and Hg, in aqueous solutions.

Cd-based compound as a multi-responsive fluorescent probe for sensing Fe cations and Cr oxyanions.

A new luminescent Cd compound, poly[[μ-1,4-bis(1H-imidazol-1-yl)benzene]{μ-5-[(3-carboxylphenoxy)methyl]isophthalato}cadmium(II)], [Cd(CHO)(CHN)] or [Cd(HL)(1,4-bib)] {HL is 5-[(3-carboxyphenoxy)methyl]isophthalic acid and 1,4-bib is 1,4-bis(1H-imidazol-1-yl)benzene}, I, has been synthesized successfully from Cd and a semirigid tricarboxylic ligand under hydrothermal conditions. Structure analysis shows that I is a two-dimensional structure with the point symbol {4.6}.

A three-dimensional twofold interpenetrated cobalt(II) MOF containing a flexible carboxylate-based ligand: synthesis, structure and magnetic properties.

The design and synthesis of coordination polymers (CPs) have attracted much interest due to the intriguing diversity of their architectures and topologies. The functional solid catena-poly[μ-aqua-triaqua{μ-5-[4-carboxyphenoxy)methyl]benzene-1,3-dicarboxylato}{μ-5-[4-carboxyphenoxy)methyl]benzene-1,3-dicarboxylato}dicobalt(II)], [Co(CHO)(HO)] or [Co(HL)(μ-HO)(HO)], was synthesized successfully by self-assembly of Co ions with 5-[(4-carboxyphenoxy)methyl]isophthalic acid (HL). The title compound was obtained under hydrothermal conditions and exhibits a twofold interpenetrated three-dimensional skeleton with hms 3,5-conn topology according to the cluster representation for valence-bonded metal-organic frameworks (MOFs).
