Two Novel Ca(II)-Carboxylate Coordination Polymers: Crystal Structures and Antimyeloma Activity Evaluation

In this study, two new coordination polymers [Ca3(BTB)2(NMP)2(H2O)2](NMP)(H2O)4 (1, H3BTB = benzene-1,3,5-tribenzoic acid, NMP = N-methyl-pyrrolidone) and [Ca3(NTB)2(DEF)2(H2O)2] (DEF)(H2O)4 (2, H3NTB = 4,4?,4?-nitrilotribenzoic acid, DEF = N,N-diethyl-formamide) based on the alkaline earth metal Ca(II) ion and two rigid C3-symmetric tricarboxylic acid ligands are successfully prepared via the solvothermal reaction. The structural analysis of complexes 1 and 2 demonstrates the existence of different topologies and structures in the as-prepared complexes because of the conformational flexibility of the organic ligands and the diverse geometry of the Ca(II)-based 1D secondary building unit. The particle sizes of these two complexes could be conveniently downsized in nanometer region via a simple treatment. In addition, in vitro anticancer activity of compounds 1 and 2 in nanometer has been studied for inhibition human myeloma cell growth via the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay.

Novel fluorescent porous hyperbranched aromatic polyamide containing 1,3,5-triphenylbenzene moieties: Synthesis and characterization

In this thesis, two novel porous hyperbranched poly(1,3,5-tris(4-carboxyphenyl) benzene p-phenylenediamine) amides with different terminal functional groups are synthesized through an A2 + B3 approach using 1,3,5-tri(4-carboxyl phenyl) benzene (H3BTB) and p-phenylenediamine as raw material, N-methyl-pyrrolidone as solvent, triphenyl phosphite and pyridine as dehydrating agent, by means of regulating the mole ratio of the monomers. The chemical structures of the prepared hyperbranched polymers are characterized by Fourier transform infrared spectroscopy and nuclear magnetic resonance (1H-NMR and 13C-NMR) analysis. These two polymers can be soluble in dimethyl sulfoxide (DMSO) and N,N-dimethyl formamide (DMF). Their DMSO solutions exhibit strong blue fluorescence, especially for the amino terminated polymer HP-NH2. While in DMF solution, the two polymers emit strong green fluorescence. These two polymers are porous polymers with the Brunauer?Emmett?Teller surface areas of 4.53 and 24.52 m2/g for HP-COOH and HP-NH2, respectively. They are potential useful in the areas of storage, separation, catalysis, and light emitting.

Room temperature CO2 fixation via cyclic carbonate synthesis over vanadium-MOF catalysts

Vanadium containing 3D MOF, MIL-47 displayed excellent synergistic catalysis with alkyl ammonium halides (TBAX) in the room temperature fixation of CO2. Theoretical intrinsic-reaction-coordinate calculations were performed at the level of M06/LACVP**++ implemented in Jaguar v8.5 software to ascertain the mechanistic pathways of catalysis. A homogeneous complex of vanadium, vanadium acetyl acetonato [VO(acac)2], was used as a model system to investigate the mechanism behind the synergistic activity of the MIL-47/TBAX, which indeed shows that the activation energy of the CO2 fixation is considerably lowered by about 30?35 kcal compared to the uncatalyzed reactions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application of 50446-44-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 50446-44-1, in my other articles.

Metal?Organic Frameworks for Biomedical Applications

Metal?organic frameworks (MOFs) are an interesting and useful class of coordination polymers, constructed from metal ion/cluster nodes and functional organic ligands through coordination bonds, and have attracted extensive research interest during the past decades. Due to the unique features of diverse compositions, facile synthesis, easy surface functionalization, high surface areas, adjustable porosity, and tunable biocompatibility, MOFs have been widely used in hydrogen/methane storage, catalysis, biological imaging and sensing, drug delivery, desalination, gas separation, magnetic and electronic devices, nonlinear optics, water vapor capture, etc. Notably, with the rapid development of synthetic methods and surface functionalization strategies, smart MOF-based nanocomposites with advanced bio-related properties have been designed and fabricated to meet the growing demands of MOF materials for biomedical applications. This work outlines the synthesis and functionalization and the recent advances of MOFs in biomedical fields, including cargo (drugs, nucleic acids, proteins, and dyes) delivery for cancer therapy, bioimaging, antimicrobial, biosensing, and biocatalysis. The prospects and challenges in the field of MOF-based biomedical materials are also discussed.

Surprising coordination for low-valent actinides resembling uranyl(vi) in thorium(iv) organic hybrid layered and framework structures based on a graphene-like (6,3) sheet topology

Three thorium(iv)-based metal-organic hybrid compounds with 2D layered and 3D framework structures exhibiting graphene-like (6,3) sheet topologies were prepared with linkers with threefold symmetry. These compounds contain rare and relatively anisotropic coordination environments for low-valent actinides that are similar to those often observed for high-valent actinide ions.

A Mesoporous Indium Metal-Organic Framework: Remarkable Advances in Catalytic Activity for Strecker Reaction of Ketones

With the aim of developing new highly porous, heterogeneous Lewis acid catalysts for multicomponent reactions, a new mesoporous metal-organic framework, InPF-110 ([In3O(btb)2(HCOO)(L)], (H3btb = 1,3,5-tris(4-carboxyphenyl)benzene acid, L = methanol, water, or ethanol), has been prepared with indium as the metal center. It exhibits a Langmuir surface area of 1470 m2 g-1, and its structure consists of hexagonal pores with a 2.8 nm aperture, which allows the diffusion of multiple substrates. This material presents a large density of active metal sites resulting in outstanding catalytic activity in the formation of substituted alpha-aminonitriles through the one-pot Strecker reaction of ketones. In this respect, InPF-110 stands out compared to other catalysts for this reaction due to the small catalyst loadings required, and without the need for heat or solvents. Furthermore, X-ray single crystal diffraction studies clearly show the framework-substrate interaction through coordination to the accessible indium sites.

Lanthanide Metal-Organic Frameworks for Luminescent Applications

Metal-organic frameworks (MOFs) have emerged as particularly exciting multifunctional hybrid materials due to their inherent advantages of both organic linkers and inorganic metal ions, as well as the tailorability in terms of structure, dimension, size, and shape. As one special type of MOF materials, the lanthanide MOFs provide the bright promise to develop various types of luminescent applications due to their unique luminescence properties such as high luminescence quantum yield, long-lived emission, large Stokes shifts, and characteristically sharp line emissions. Up to now, lanthanide MOFs have been proven successful in many applications. In this chapter, we review the latest developments in lanthanide MOFs and their applications in sensing, light-emitting devices, and biomedicine. In addition, we highlight some strategies for effectively improving their luminescent function applications.
