Microporous Metal-Organic Framework Based on a Bifunctional Linker for Selective Sorption of CO2 over N2 and CH4 was written by Chen, Di-Ming;Zhang, Xiao-Ping;Shi, Wei;Cheng, Peng. And the article was included in Inorganic Chemistry in 2015.Electric Literature of C9H7N3O2 This article mentions the following:
A bifunctional organic linker 4-(4-carboxyphenyl)-1,2,4-triazole (HCPT), incorporating both carboxylate and triazole groups, was successfully used in the construction of a 2-fold interpenetrated dynamic metal-organic framework (MOF), {[Cu3(CPT)4(μ3-OH)]·NO3·7H2O·EtOH}n (1) based on a triangular Cu(II)-hydroxo cluster as secondary building unit (SBU). Upon solvation/desolvation and temperature, the crystal cell parameters of 1 could be fine-tuned. More importantly, a transformation from disordered phase to a more ordered phase after activation was observed via a single-crystal-to-single-crystal mode. Gas sorption studies reveal that the activated 1 exhibits highly selective sorption of CO2 over N2 and CH4 at room temperature In the experiment, the researchers used many compounds, for example, 4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2Electric Literature of C9H7N3O2).
4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2) belongs to triazole derivatives. However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to azides. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.Electric Literature of C9H7N3O2
