A monolithic, highly electrochemically efficient Re-based metal-organic framework (MOF) thin film has been deposited onto a conductive FTO electrode by liquid-phase epitaxy. The X-ray diffraction (XRD) analysis reveals the presence of a highly oriented film grown exclusively along the [001] direction. This epitaxially-grown SURMOF exhibits an extremely high faradaic efficiency of 93 ± 5% when operated as an electrocatalyst for the reduction of CO2 to CO. In addition, the obtained current densities of the high-quality monolithic coatings exceed 2 mA cm-2, a value at least one order of magnitude larger than that reported for previous electrocatalytically active MOF thin films.

Four metal complexes [Pd(L1)Cl2·2H 2O] (1), [Pt(L1)Cl2·2H2O] (2), [Pd(L2)Cl2·H2O] (3) and [Pt(L 2)Cl2·H2O] (4) (L1 = 2,2?-bipyridyl-5,5?-dicarboxylic acid, L2 = 2,2?-bipyridyl-4,4?-dicarboxylic acid) have been synthesized under hydrothermal conditions and fully characterized by IR and 1H-NMR spectra, elemental analysis, and X-ray single crystal diffraction analysis. Interactions of these complexes with fish sperm DNA (FS-DNA) were investigated using UV-Vis absorption and fluorescence spectroscopic methods. Further insight was brought by quantum chemistry calculations by means of G03 package and taking B3LYP functional Lanl2dz Gen basis set. Agarose gel electrophoresis run on pBR322 plasmid DNA gave proof that all four complexes exhibit efficient DNA cleavage. Complexes 1-4 manifested cytotoxic specificity and a significant cancer cell inhibitory rate. Independent apoptosis tests under the light microscope, performed on hematoxylin-eosin stained HeLa cells, evidenced morphological changes induced by all the complexes.

Abstract Collagen is the most abundant protein in animals. A variety of indications are associated with the overproduction of collagen, including fibrotic diseases and cancer metastasis. The stability of collagen relies on the posttranslational modification of proline residues to form (2S,4R)-4-hydroxyproline. This modification is catalyzed by collagen prolyl 4-hydroxylases (CP4Hs), which are Fe(II)- and alpha-ketoglutarate (AKG)-dependent dioxygenases located in the lumen of the endoplasmic reticulum. Human CP4Hs are validated targets for treatment of both fibrotic diseases and metastatic breast cancer. Herein, we report on 2,2?-bipyridinedicarboxylates as inhibitors of a human CP4H. Although most 2,2?-bipyridinedicarboxylates are capable of inhibition via iron sequestration, the 4,5?- and 5,5?-dicarboxylates were found to be potent competitive inhibitors of CP4H, and the 5,5?-dicarboxylate was selective in its inhibitory activity. Our findings clarify a strategy for developing CP4H inhibitors of clinical utility.

Transfer and inversion of supramolecular chirality from chiral calix[4]arene analogs (3D and 3L) with an alanine moiety to an achiral bipyridine derivative (1) with glycine moieties in a coassembled hydrogel are demonstrated. Molecular chirality of 3D and 3L could transfer supramolecular chirality to an achiral bipyridine derivative 1. Moreover, addition of 0.6 equiv of 3D or 3L to 1 induced supramolecular chirality inversion of 1. More interestingly, the 2D-sheet structure of the coassembled hydrogels formed with 0.2 equiv of 3D or 3L changed to a rolled-up tubular structure in the presence of 0.6 equiv of 3D or 3L. The chirality inversion and morphology change are mainly mediated by intermolecular hydrogen-bonding interactions between the achiral and chiral molecules, which might be induced by reorientations of the assembled molecules, confirmed by density functional theory calculations.

Interpenetration in metal-organic frameworks (MOFs), where multiple nets of metal ions or clusters linked by organic ligands are nested within each other’s pore spaces, affects important physical properties such as stability and gas uptake, and can be controlled through ligand sterics and modifying synthetic conditions. Herein, we extend the use of coordination modulation-deliberate addition of competing monotopic ligands to syntheses-To prepare Sc MOFs containing related biphenyl-4,4?-dicarboxylate (bpdc) and 2,2?-bipyridine-5,5?-dicarboxylate (bpydc) linkers. The Sc-bpdc MOF adopts a two-fold interpenetrated structure, however, the Sc-bpydc MOF is non-interpenetrated, despite only minor electronic modifications to the ligand. A comprehensive experimental and theoretical examination reveals that ligand twisting (energetically favourable for bpdc but not bpydc) and associated pi-stacking interactions are a prerequisite for interpenetration. The more rigid Sc-bpdc is susceptible to modulation, resulting in differences in morphology, thermal stability and the synthesis of a highly defective, acetate-capped mesoporous material, while the large pore volume of Sc-bpydc allows postsynthetic metallation with CuCl2 in a single-crystal to single-crystal manner. Controlling interpenetration through linker conformation could result in design of new materials with desirable properties such as bifunctional solid-state catalysts.

Solid-state electrochemiluminescence (ECL) has drawn increasing attention due to its advantages over solution-phase ECL, such as reducing the consumption of expensive reagents and enhancing the ECL signal. Herein we report a ruthenium(ii)-polypyridyl doped zirconium(iv) metal-organic framework (MOF) film, UiO-67-Ru@FTO, for solid-state electrochemiluminescence. With tripropylamine (TPA) as a coreactant, UiO-67-Ru@FTO exhibited high ECL intensity and good stability. A linear relationship was found between the ECL intensity and TPA concentration in a wide range of 0.04-20 mM. Additionally, UiO-67-Ru@FTO was successfully used for dopamine detection, implying its great potential in real-life applications.

Postsynthetic metalation (PSM) has been employed as a robust method for the postsynthetic modification of metal-organic frameworks (MOFs). However, the lack of relevant information that can be obtained for the postsynthetically introduced metallic ions has hindered the development of PSM applications. Thanks to the advancement in single-crystal X-ray diffraction (SCXRD) technology, there have been a few recent examples in which successful postsynthetic introduction of single metal ions into MOFs occurred at the defined chelating sites. These works have provided useful explanations about the complicated host-guest chemistry involved in PSMs. On the other hand, there are only limited examples with crystallographic snapshots of the postsynthetic installation of metal clusters into the pores of MOFs using an ordinary SCXRD due to the loss of crystallinity of parent matrix during the PSM process. Herein, by the careful selection of starting materials and controlling the reaction conditions, we report the first crystallographic visualization of metal clusters inserted into Zr-based MOFs via PSM. The structural advantages of the parent Zr-MOF, which are inherited from the stable Zr6 cluster and triazole-containing dicarboxylate ligand, ensure both the preservation of high crystallinity and the presence of flexible coordination sites for PSM. Furthermore, PSM of metal clusters in a MOF pore space enhances stability of the final samples while also imparting the functionality of a successful catalyst toward ethylene dimerization reaction. The related construction ideas and structural information detailed in this work can help lay the foundation for further advancements using the postmodification of MOFs as well as open new doors for the utilization of SCXRD technology in the field of MOFs.

RhL2 complexes of phosphonate-derivatized 2,2?-bipyridine (bpy) ligands L were immobilized on titanium oxide particles generated in situ. Depending on the structure of the bipy ligand?number of tethers (1 or 2) to which the phosphonate end groups are attached and their location on the 2,2?-bipyridine backbone (4,4?-, 5,5?-, or 6,6?-positions)?the resulting supported catalysts showed comparable chemoselectivity but different kinetics for the hydrogenation of 6-methyl-5-hepten-2-one under hydrogen pressure. Characterization of the six supported catalysts suggested that the intrinsic geometry of each of the phosphonate-derivatized 2,2?-bipyridines leads to supported catalysts with different microstructures and different arrangements of the RhL2 species at the surface of the solid, which thereby affect their reactivity.

The interfaces of Cu/ZnO and Cu/ZrO2 play vital roles in the hydrogenation of CO2 to methanol by these composite catalysts. Surface structural reorganization and particle growth during catalysis deleteriously reduce these active interfaces, diminishing both catalytic activities and MeOH selectivities. Here we report the use of preassembled bpy and Zr6(mu3-O)4(mu3-OH)4 sites in UiO-bpy metal-organic frameworks (MOFs) to anchor ultrasmall Cu/ZnOx nanoparticles, thus preventing the agglomeration of Cu NPs and phase separation between Cu and ZnOx in MOF-cavity-confined Cu/ZnOx nanoparticles. The resultant Cu/ZnOx@MOF catalysts show very high activity with a space-time yield of up to 2.59 gMeOH kgCu-1 h-1, 100% selectivity for CO2 hydrogenation to methanol, and high stability over 100 h. These new types of strong metal-support interactions between metallic nanoparticles and organic chelates/metal-oxo clusters offer new opportunities in fine-tuning catalytic activities and selectivities of metal nanoparticles@MOFs.
