A Novel Azo-Linked Polymer Bearing Trifluoromethyl Groups for I Capture.

In this work, a novel three nitro-group-bearing monomer 3,6-dinitro-9-(2-trifluoromethyl-4-nitrophenyl)-carbazole (Car-3NO -CF ) via a CN coupling reaction between 3,6-dinitro-9H-carbazole (Car-2NO ) and 2-chloro-5-nitrobenzotrifluoride is synthesized, and obtained single crystal and single crystal analysis data for this compound. The crystal system of Car-3NO -CF is monoclinic and it has a P 21/c space group. This new monomer (Car-3NO -CF ) is also utilized to synthesize a novel azo-linked polymer (Azo-Car-CF ).

Cu-Organic framework-derived V-doped carbon nanostructures for organic dye removal.

Metal-organic frameworks (MOFs) have recently emerged as a type of uniformly and periodically atom-distributed precursor and efficient self-sacrificial template to fabricate hierarchical porous-carbon-related nanostructured functional materials. In this work, we used Cu(II) ions and aromatic dicarboxylic acid to construct [Cu(4,4'-oba)(μ-OH)(HO)] (4,4'-Hoba = 4,4'-oxybisbenzoic acid) as a precursor for the preparation of carbon nanostructures. Doping foreign elements into intrinsic MOF-based nanomaterials is an effective way to enhance the adsorption property and photocatalytic activity; thus, we designed a facile method to synthesize a vanadium-doped mixture of CuO and Cu nanoparticles encapsulated in a Cu-MOF-derived carbon nanostructure (C-V-1) in this work for the first time.

A novel 3D Zn-coordination polymer based on a multiresponsive fluorescent sensor demonstrating outstanding sensitivities and selectivities for the efficient detection of multiple analytes.

A novel and unusual 3D luminescent coordination polymer (CP) [Zn(3-bpah)(bpta)(HO)]·3HO (1), where 3-bpah denotes ,'-bis(3-pyridinecarboxamide)-1,2-cyclohexane and Hbpta denotes 2,2',4,4'-biphenyltetracarboxylic acid, was successfully synthesized hydrothermal methods from Zn(II) ions and 3-bpah and bpta ligands. The structure of this CP was investigated powder X-ray diffraction (PXRD) analysis along with single crystal X-ray diffraction. Notably, 1 exhibits remarkable fluorescence behavior and stability over a wide pH range and in various pure organic solvents.

Efficient and selective removal of Congo red by a C@Mo composite nanomaterial using a citrate-based coordination polymer as the precursor.

To research the effect of structural diversity on citrate-based coordination polymers (CPs), citric acid (H4cit) was selected to combine with Cu(ii) under hydrothermal conditions. A new CP [Cu2(cit)(H2O)2] (1) was synthesized and structurally characterized. The title complex shows a 3D 2,4,6-connected topology with the point symbol of {43·63}{44·66·85}{4}.
