Two isostructural CoII-based metal-organic frameworks (MOFs) with the opposite framework charges were constructed, which can be simply controlled by changing the tetrazolyl or triazolyl terminal in two bifunctional ligands. Notably, the cationic MOF {[Co6(OH)2(INA)6(CPT)3](NO3)(DMA)8}n 2 can adsorb much more C2H2 than the anionic MOF {[Co6(OH)2(INA)6(TZB)3](H2NMe2)2(DMA)7}n (1) with an increase of 88% for C2H2 uptake at 298 K in spite of more active nitrogen sites in 1 (HINA = isonicotinic acid, H2TZB = 4-(1H-tetrazol-5-ye)benzoic acid, HCPT = 4-(4-carboxyphenyl)-1,2,4-triazole). Theor. calculations indicate that both nitrate and triazolyl play vital roles in C2H2 binding and the C2H2 adsorption isotherm confirms that the enhanced C2H2 uptake for 2 (225 and 163 cm3g-1 at 273 and 298 K) is exceptionally high for MOF materials without open metal sites or uncoordinated polar atom groups on the frameworks. In the experiment, the researchers used many compounds, for example, 4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2Computed Properties 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. Triazole growth retardants such as uniconazole and paclobutrazol have been known to inhibit the biosynthesis of gibberellins by blocking kaurene oxidase, an P450 enzymeComputed Properties of C9H7N3O2
