A functional Cu(I) boron imidazolate framework (BIF) with a ladder-chain structure can not only change to another single-chain structure by incorporating 4,4'-bipyridine, but can also act as a reducing agent to load trimetal Au-Ag-Pd nanoparticles directly; the BIF with loaded noble NPs showed an excellent reduction effect on 4-nitrophenol. Moreover, we obtained a porous borocarbonitride by the direct carbonisation of this low-dimensional BIF. The resulting porous borocarbonitride exhibits fast adsorption behavior for 4-nitrophenol and can be a high-temperature conductor.

The production of hydrogen peroxide (H2O2) through two-electron oxygen reduction reaction (2e- ORR) has emerged as a more environmentally friendly alternative to the traditional anthraquinone method. Although oxidized carbon catalysts have intensive developed due to their high selectivity and activity, the yield and conversion rate of H2O2 under high overpotential still limited. The produced H2O2 was rapidly consumed by the increased intensity of H2O2 reduction, which could ascribe to decomposition of peroxide radicals under high voltage in the carbon catalyst.

The expression of Klebsiella pneumoniae carbapenemase (KPC), a type of carbapenem-hydrolyzing β-lactamase, in Gram-negative bacteria has caused significant bacterial resistance to carbapenems, the antibiotic of last resort. Herein, we describe the discovery of 2-carboxyquinoline boronic acids as inhibitor of KPC. We have identified fluoro-substituted carboxyquinoline boronic acids 1e as the most potent inhibitor, with an IC50 of 8.

Herein, we have established the formation of diaryl amide by aminocarbonylation of nitrobenzene with boronic acids. The method works in the catalytic presence of economical and commercially available CuI salt, which was significantly promoted by the FeSe(CO) cluster. Mo(CO) serves as a source of CO, and it also acts as a reductant with a combination of iron cluster.

Coordination between 5,5',6,6'-tetrahydroxyindigo (4OH-ID) and boron tribromide unexpectedly affords a novel dynamic covalent polymer, namely P(ID-O-B), consisting of alternating indigo and indigo diradicaloid units. The catechol-boron dynamic bond plays a vital role in promoting the diradicaloid formation and stabilizing the formed diradicaloid segments. The diradicaloid segment in the polymer has a triplet ground state and a thermally populated doublet state, which has been confirmed by the EPR study.
