The salen-Co(iii) motif was inserted into imidazolium-functionalized multivariate cationic zirconium metal-organic frameworks (MOFs). The salen-Co(iii), as a Lewis acid site, and the Br- of imidazolium, as a nucleophile, are synergistically catalytic for the enhanced cycloaddition reaction of carbon dioxide with epoxides.

A homochiral lamellar supramolecular host system has been developed by treating 3-[(E)-{[(1R,2R)-2-aminocyclohexyl]imino}methyl]-4-hydroxybenzoic acid (H2L) with copper nitrate and characterized by a variety of techniques including microanalysi

G-quadruplex (G4) DNA structures are involved in many important biological processes and can be linked to several human diseases. Drug-like low molecular weight compounds that target G4 structures are therefore interesting not only for their potential therapeutic properties but also for their potential use as chemical research tools. We report here on the development of methods to synthesize spiropyrans using a condensation-cyclisation reaction of quaternary salts of α-methyl quinoline or phenanthridine with salicylaldehydes. Evaluation of the synthesized phenanthridine spiropyrans' interactions with G4 DNA was performed with a Thioflavin T displacement assay, circular dichroism, Taq DNA polymerase stop assay, and NMR. This revealed that the substitution pattern on the phenanthridine spiropyrans was very important for their ability to bind and stabilize G4 structures. Some of the synthesized low molecular weight spirocyclic compounds efficiently stabilized G4 structures without inducing structural changes by binding the first G-tetrad in the G4 structure.

A large excess of unlabeled ligands over gallium-67 (67Ga) provides 67Ga-labeled probes with high radiochemical yields in a short reaction time. However, the unlabeled ligands hinder target accumulation of radiolabeled probes by comp

Two new mixed-metal clusters {CuM2(H2O)2[Cu(C14H16N2O3)Cl]6}·H2O (M = Mn 1, Zn 2) based on Schiff-base ligands were designed and synthesized by the reaction of 1,2-cyclohexanediamine-N,N′-bis-(3-carboxylsalicylide), copper chloride and zinc chloride or manganese chloride under solvothermal conditions. They were characterized by various techniques including single-crystal X-ray diffraction, powder X-ray diffraction (XPRD), elemental analysis, TG analysis, IR and UV-visible spectroscopy. Compounds 1 and 2 are isostructural, and display an interesting windmill-type structure built from a trinuclear mixed-metal center [CuM2(CO2)6(H2O)2] (M = Mn 1, Zn 2) linked with six [CuLCl] (L = C14H16N2O3) units. The oxidation of cyclohexene catalysed by 1 and 2 as heterogeneous catalysts was investigated and showed high activity. In addition, a magnetic study indicates that antiferromagnetic interactions exist in compound 1.

Photocatalytic hydrogen production via water splitting has attracted much attention for future clean energy application. Herein we report a noble-metal-free photocatalytic hydrogen production system containing a simple bidentate cobalt Schiff base complex as the molecular cocatalyst, CdS nanorods as the photosensitizer, and ascorbic acid as the electron donor. The system shows highly enhanced photocatalytic activity compared to pure CdS NRs under visible light (λ > 420 nm). Under optimal conditions, the turnover numbers (TONs) for hydrogen production reached ～15 200 after 12 hours of irradiation, and an apparent quantum yield of ～27% was achieved at 420 nm monochromatic light. Steady-state photoluminescence (PL) spectra indicated efficient charge transfer between the excited CdS NRs and the cobalt cocatalyst for improved hydrogen production. Spectroscopic studies of the photocatalytic reaction revealed the reduction of the Co(ii) complex to Co(i) species, which are probably active intermediates for hydrogen evolution. On the basis of the spectroscopic studies, we propose a reaction mechanism for hydrogen production in the present photocatalytic system.

A copper-mediated Duff reaction for ortho-selective formylation of phenols has been developed. In the presence of copper species, significant improvements of yield and ortho-selectivity of the Duff formylation were achieved, which provides an easy access to salicylaldehydes from phenols.
