with amino-and pyridine-functionalized pores has been successfully constructed under solvothermal conditions by using the mixed-ligand strategy, which consists of twisty 6 3 layers pillared by datz − ligands. The adsorption properties of this MOF were studied by CO 2 , N 2 , and CH 4 sorption measurements. Compared with the analogous 4,4′-bipyridine (bpy) pillared MOF {Zn(bpydb)(bpy)} n (2) we reported earlier, the activated 1 showed enhanced CO 2 sorption capacity and good sorption selectivity for CO 2 over N 2 and CH 4 at room temperature.

The conversion of CO2 into high value-added chemical products is the focus of current scientific research. We make use of the specific porous structure of nanosized metal–organic frameworks (MOFs) loading the highly active yet metastable nano Cu2O to catalyze the conversion of CO2 into a series of high value-added bioactive pyridone/pyrone-3-carboxylic acid products via heterocyclic 4-hydroxy-2-pyridones/pyrones, which exhibit high activity, selectivity, and reusability. Nano MOF sponge-covered metastable nanoparticles (NPs) converting CO2 into high value-added bioproducts provide a facile “dual-side surfactant” strategy, a highly efficient composite catalyst, and a practicable pathway not only for the sustainable use of CO2 but also for environment-friendly production of bioproducts.

A new method of introducing a ‘lock’ ligand into the frame of MOFs is described to achieve the first example of a MOF-based biosensor for the recognition and distinction of S-containing amino acids.
