“…Different flexible ligands [9][10][11] as well as halides or pseudohalides [3,[12][13][14] have been widely used for this purpose. Among them, we focused to Schiff bases with a flexible spacer between iminic nitrogen atoms, which are suitable for this matter [7][8][9], especially when completed with the pseudohalide NCSknown to coordinate to copper(I) ions in an end-to-end bridging mode [3,13,14].…”

Nano-sized powder of a new 1D copper(I) coordination polymer, [Cu(nba2en)(NCS)]n (1), (nba2en = N,Nʹ-bis(4-ntrobenzylidene)ethane-1,2-diamine, was synthesized using ultrasonic bath assisted and characterized by scanning electron microscopy (SEM), IR and 1 H-NMR spectroscopy, and elemental analyses. Thermal stability of 1 was studied using thermogravimetric (TG) and differential thermal analyses (DTA). The crystal structure was investigated by single-crystal X-ray diffraction. The structure of 1 consists of a 1D polymeric chain in which copper(I) ions are bridged by two thiocyanate group bonding in an end-to-end fashion, with CuCu separation 5.556(4) Å.

“…Because of the fast reaction between metal and ligand sources, obtaining a high-quality single-crystal is still a time-consuming and challenging step in the MOF synthesis process. To fix the problem, some crystallization methods, such as solvent layering and crystallization in gels, − as well as in situ formation of starting materials which reduce the combination rate of the reagents can be applied. , In this regard and in continuation of our research activity on the exploration of effective factors on the design, synthesis, and potential applications of new CPs, − in this work, in situ ligand formation and subsequent MOF crystallization in a one-pot reaction has been examined. In this approach, a tetracarboxylate linker, 1,2,4,5-benzene tetracarboxylic acid, has been gradually obtained via hydrolysis of pyromellitic dianhydride and formed a new zinc(II)-based MOF crystal under solvothermal conditions.…”

A new highly fluorescent zinc–organic framework [Zn 2 (btca)(DMSO) 2 ] n ( Zn-MOF ) was prepared via in situ ligand formation by the solvothermal reaction of Zn(NO 3 ) 2 ·6H 2 O and pyromellitic dianhydride (PMDA) in DMSO solvent. During the solvothermal reaction, PMDA was gradually hydrolyzed to a pyromellitic acid, 1,2,4,5-benzene tetracarboxylic acid (H 4 btca), to provide a tetracarboxylic acid as a linker in the reaction medium. Single-crystal X-ray diffraction analysis exhibits a 3D porous structure with open tetragonal channels running along the crystallographic c -axis. The Zn-MOF was explored as an on-mode fluorescent sensor for tracing cimetidine in biological fluids and pharmaceutical samples in the presence of interfering species. The results show a quick response in a short time range. The characteristics of this sensor were investigated by field-emission scanning electron microscopy, dynamic light scattering, energy-dispersive X-ray analysis, powder X-ray diffraction, Fourier transform infrared and UV–vis spectroscopy as well as thermogravimetric, and elemental analyses.

“…Our recent research results show that even nonporous CuI-based coordination polymers can rapidly capture volatile iodine in the gas phase . On the basis of our experience on the design and synthesis of copper(I) coordination polymers, ,,− here we investigated the effect of different bispyrazolyl ligands (Scheme ) on the assembly of nonporous coordination polymers of copper(I) hexafluorophosphate and characterized three novel compounds. In addition, vapor iodine absorption ability by the synthesized compounds was checked and related to their structure features.…”

Three cationic non-porous copper(I) coordination polymers containing bis-pyrazolyl flexible ligands have been prepared and characterized, namely {[Cu(μ-bdb) 1.5 ](PF 6)} n (1), {[Cu(μbpb) 2 ](PF 6)} n (2) and {[Cu(μ-bpmb) 2 ](PF 6)} n (3) (bdb = 1,4-bis(3,5-dimethylpyrazolyl) methyl)benzene; bpb = 1,4-bis(pyrazolyl)butane; bpmb = 1,4-bis(pyrazolyl) methyl)benzene). All compounds were characterized by IR, PXRD, elemental and thermal analyses, and singlecrystal X-ray diffraction. Compound 1, with methyl-substituted pyrazolyl ligand, forms a chain of alternating rings and ribbons in which the copper(I) centers are three coordinated in distorted trigonal planar geometry. In compounds 2 and 3 copper(I) atoms adopt distorted tetrahedral geometries giving two dimensional sheet structures with 4 4-sql topology. Interestingly, iodine sorption experiments show that colorless crystals of 2 and 3 remain unchanged in the presence of iodine vapors, while the three coordinated compound 1 immediately absorb iodine and turn dark. Anion exchange behavior of compounds 1 and 2 was also investigated both in solution and in solid state.
