On July 5, 2017, Huang, Hubiao; Sato, Hiroshi; Aida, Takuzo published an article.Application In Synthesis of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate The title of the article was Crystalline Nanochannels with Pendant Azobenzene Groups: Steric or Polar Effects on Gas Adsorption and Diffusion?. And the article contained the following:
An azobenzene-containing, zirconium-based metal-organic framework (AzoMOF), upon irradiation with UV light at 365 ± 10 nm, underwent trans-to-cis isomerization of its azobenzene pendants to furnish the cis-isomer content of 21% (AzoMOF21%) in 30 min at the photostationary state and underwent backward isomerization into AzoMOF1% upon either irradiation with visible light (420-480 nm) or heating. When the cis-isomer content increased, the diffusion rate and amount of CO2 adsorbed into the nanochannels of AzoMOF decreased considerably. When erythrosine B, a polarity-probing guest, was used, it showed a red shift upon exposure of AzoMOF20%⊃EB to visible light, indicating that the interior environment of AzoMOF turns less polar as the trans-isomer content becomes higher. In sharp contrast, the adsorption profiles of AzoMOF15% and AzoMOF1% for Ar having an analogous kinetic diameter to CO2 but no quadrupole moment and a smaller polarizability were virtually identical to one another. Therefore, it is likely that CO2 experiences a dominant effect of a polar effect rather than a steric effect in the crystalline nanochannels. The experimental process involved the reaction of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate(cas: 1312703-30-2).Application In Synthesis of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate
