摘要

Five coordination polymers bearing 2-p-methoxyphenyl-1H-imidazole-4,5-dicarboxylic acid (H3MOP-hIDC) formulated as [Zn-2(mu(2)-HMOPhIDC)(2)(phen)(2)](n) (phen = 1,10-phenanthroline) (1), [X(mu 2-HMOP-hIDC)(2,2'-bipy)](n) (X = Ni (2) and Mn (3), 2,2'-bipy = 2,20-bipyridine) and {[M(mu(2)-H2MOPhIDC)(2)]center dot 2H(2)O}(n) (M = Mn (4) and Co (5)) have been synthesized under hydrothermal conditions. Their molecular structures have been determined by IR spectra, elemental analyses, thermogravimetric analyses, powder X-ray diffraction, and further characterized by single-crystal X-ray diffraction. Complex 1 features an infinite corrugated structure. Complexes 2 and 3 display straight chains. Both complexes 4 and 5 exhibit isomorphous 2D structures containing similar inorganic motifs with an individual rhombus as secondary building unit. The photoluminescent behaviors of these complexes have also been investigated. (c) 2012 Elsevier B.V. All rights reserved.

High and Tunable Proton Conduction in Six 3D-Substituted Imidazole Dicarboxylate-Based Lanthanide-Organic Frameworks

Ruilan Liu, Yi-Hong Yu, Hong-Wei Wang, Yu-Yang Liu, Gang Li

Summary: Six isostructural three-dimensional Ln(III)-organic frameworks were fabricated using a multifunctional ligand H3MIDC, exhibiting humidity- and temperature-dependent proton conductivity. The proton conductivity systematically enhances with decreasing ionic radius, suggesting that lanthanide contraction tactics effectively regulate proton conductivity. These Ln-MOFs show promising potential for future applications due to their water and electrochemical stability.

Dynamics and Proton Conduction of Heterogeneously Confined Imidazole in Porous Coordination Polymers

Linkun Cai, Junsheng Yang, Yuyan Lai, Yuling Liang, Rongchun Zhang, Cheng Gu, Susumu Kitagawa, Panchao Yin

Summary: The confinement of proton carrier molecules in nanostructures can reduce their proton dissociation energy. However, restricted molecular motion from surface attraction impedes the easy transportation of free protons. To address this issue, imidazole is confined in the channels of porous coordination polymers with tunable geometries, and its electric/structural relaxations are measured. Imidazole confined in square-shaped channels exhibits heterogeneity in dynamics with a core-shell-cylinder model. The dimensions and geometry of the nanochannels play a crucial role in shielding the blocking effect from attractive surfaces and facilitating the filling of internal proton carrier molecules, leading to enhanced dynamics and proton conductivity.

Coordination Stoichiometry Effects on the Binding Hierarchy of Histamine and Imidazole-M2+ Complexes

Jake Song, Eesha Khare, Li Rao, Markus J. Buehler, Niels Holten-Andersen

Summary: Rheology experiments and density functional theory calculations were used to characterize the stability of coordination complexes between histamine and imidazole with Ni2+, Cu2+, and Zn2+. It was found that the binding hierarchy is driven by the specific affinity of the metal ions to different coordination states, which can be macroscopically tuned by changing the metal-to-ligand stoichiometry. These findings facilitate the rational selection of metal ions for optimizing the mechanical properties of metal-coordinated materials.

Yu-Jie Liang, Liu Liu, Jun Yao, Min Deng, Quan-Qing Xu, Ai-Xin Zhu, Bo Huang

Summary: Two new zinc-triazole-carboxylate frameworks were synthesized using a thiophene-containing dicarboxylate and two different triazole ligands. Compound 1 is a 3D anionic porous framework based on dinuclear Zn(II) tetracarboxylate paddlewheel SBUs and dinuclear [Zn-2(tz)(2)] subunits, while compound 2 is a neutral 3D framework based on Zn-triazolate layers and dicarboxylate pillars. Both frameworks exhibit irreversible solid-state structural transformations upon solvent removal/uptake, and show CO2-induced, gate-opening adsorption isotherms at 195 K. Compound 1 selectively adsorbs cationic dyes, while compound 2 hardly adsorbs any selected dyes.

Kinetic Trapping of Photoluminescent Frameworks During High-Concentration Synthesis of Nonemissive Metal-Organic Frameworks

Arjun Halder, David C. Bain, Tristan A. Pitt, Zixiao Shi, Julia Oktawiec, Jung-Hoon Lee, Stavrini Tsangari, Marcus Ng, Jose J. Fuentes-Rivera, Alexander C. Forse, Tomce Runcevski, David A. Muller, Andrew J. Musser, Phillip J. Milner

Summary: Metal-organic frameworks (MOFs) are porous materials with potential applications in gas separation, drug delivery, sensing, and catalysis. This study demonstrates that increasing the reaction concentration during the synthesis of MOFs leads to the unexpected trapping of a new framework called CORN-MOF-1. The structure of CORN-MOF-1 is similar to that of known MOFs, but with partially protonated linkers and charge-balancing or coordinated formate groups. CORN-MOF-1 exhibits strong photoluminescence in the solid state, while other MOFs show weak emissive properties due to excimer formation.

An RNA-based catalytic hairpin assembly circuit coupled with CRISPR-Cas12a for one-step detection of microRNAs

Pinru Chen, Luying Wang, Peipei Qin, Bin-Cheng Yin, Bang-Ce Ye

Summary: In this study, a one-step detection method for microRNAs based on the RNA-based catalytic hairpin assembly (CHA) circuit coupled with CRISPR-Cas12a was proposed. The target miRNA can specifically trigger RNA-based CHA and induce a configurational change of the blocked crRNAs into precursor crRNAs (pre-crRNAs), which can be processed into mature crRNAs to function by leveraging the inherent RNase activities of Cas12a. The developed circuit achieves a femtomolar detection limit and shows accurate detection of miRNA levels in different cell lines.

Angela Lis, Viorica Gladchi, Gheorghe Duca, Sergey Travin

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Geometric control of Cu, Ni and Pd complexes in the solid state via intramolecular H-bonding interactions

Ankita Puri, Allison Mcaninch, Sheng Shu, Khashayar Rajabimoghadam, Maxime A. Siegler, Marcel Swart, Isaac Garcia-Bosch

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
