Quality Control of 5,5′-Dimethyl-2,2′-bipyridine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Controlling the Synthesis of Metal-Organic Framework UiO-67 by Tuning Its Kinetic Driving Force.

The successful synthesis of metal-organic framework (MOF) compounds relies on an intricate interplay between the components of the synthesis liquor at the given synthesis conditions. The interdependence of modulator, linker, and solvent amounts in the synthesis of the Zr-based MOF, UiO-67, is explored. Probably control of linker vacancy defects in UiO-67 is feasible by tuning the ratios of these components, and such control derives from recognizing the kinetic driving forces during MOF crystal growth. Linker vacancy defects (and modulator mols. occupying linker sites) can be reduced by limiting the solvent amount to maintain a saturated concentration of linker throughout the synthesis. The method enables formation of UiO-67 with an ideal 1:1 ratio between Zr and the 4,4′-biphenyldicarboxylic acid linker, without surplus linker in the mother liquor or addnl. post-synthetic steps, and reduces the amount of DMF solvent to <20% the amount in previously reported procedures.
