And the article was included in Angewandte Chemie, International Edition in 2022.Quality Control of Cuprichydroxide This article mentions the following:
The degree of pore filling is an important parameter for defining guest@MOF properties in applications including electronics, optics, and gas separation However, the interplay of key aspects of host-guest interactions, such as a quant. description of the guest alignment or the structural integrity of the host as function of pore filling are yet to be determined Polarisation-dependent IR spectroscopy in attenuated total reflection configuration combined with gas sorption allowed to simultaneously study the orientation of the guest mol. and structural changes of the MOF framework during the pore filling process. Thereby we found, that initially randomly oriented guest mols. align with increasing pore filling during adsorption from the gas phase. At the same time, the framework itself undergoes a reversible, guest mol.-dependent rotation of the aromatic linker and a linker detachment process, which induce defects. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Quality Control of Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to the earth-abundant, inexpensive and low toxicity. Copper nanoparticles can catalyze the Ullmann coupling reaction in a wide range of applications.Quality Control of Cuprichydroxide
