Astute combination of basic functionality and luminescence property can pursue multifunctional metal-organic frameworks (MOFs) with assorted applications such as selective CO₂ adsorption, specific detection of explosive nitro compounds, and toxic metal ion sensing. The bifunctional ligand 4-(4-carboxyphenyl)-1,2,4-triazole (HL) is used to build the framework [Cd(L)₂]璺?DMF)_0.92 (1) (L = L^-1, DMF = N,N’-dimethylformamide), having a free N atom decorated porous channel. The solvothermal synthesis is extended to produce three isoskeletal frameworks in diverse solvents, where pore size maximizes in 2 by employing N,N’-diethylformamide solvent. The activated framework [Cd(L)₂] exhibits strong CO₂ affinity with good CO₂/N₂ selectivity, and shows min. CO₂ loss during five adsorption-desorption cycles. Sensing studies for nitro-aromatic compounds in DMF reveal highly specific detection of 2,4,6-trinitophenol (TNP) with remarkable quenching (K_SV = 9.3 鑴?10⁴ M^-1) and low limit of detection (LOD: 0.3 ppm). The quenching mechanism is ascribed to the combined existence of static and dynamic quenching plus resonance energy transfer. The activated framework further shows highly selective luminescent detection of Cu²⁺ ions with a quenching constant of 4.4 鑴?10³ M^-1 and very low LOD of 3.9 ppm. The detection of Cu²⁺ ions accompanies a visible color change in solution and solid phase, which validates the present system as a potential colorimetric Cu²⁺ sensor. Of note is that bifunctional sensor shows excellent reusability toward TNP and Cu²⁺ detection. Overall, selective and multicycle CO₂ adsorption, together with efficient sensing of both TNP and Cu²⁺ ion, manifest this pore-functionalized MOF as a versatile material for sustainability. In the experiment, the researchers used many compounds, for example, 4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2COA of Formula: C9H7N3O2).

4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2) belongs to triazole derivatives. Triazoles exhibit substantial isomerism, depending on the positioning of the nitrogen atoms within the ring. Triazoles are compounds with a vast spectrum of applications, varying from materials (polymers), agricultural chemicals, pharmaceuticals, photoactive chemicals and dyes.COA of Formula: C9H7N3O2

And the article was included in Polyhedron in 2022.Computed Properties of C9H7N3O2 This article mentions the following:

Hydrogen-bonded supramol. frameworks remain highly interesting for the development of novel porous materials. Herein a hydrogen-bonded supramol. framework of a cobalt(II) complex, [Co(cpt)₂(H₂O)₂] (Hcpt = 4-(p-carboxyphenyl)-1,2,4-triazole), was synthesized and structurally characterized. A single crystal X-ray diffraction (SC-XRD) study indicates that the monometallic Co²⁺ ion is located in a distorted octahedral geometry and the complex forms a two-dimensional supramol. network stabilized by significant intermol. N···H interactions. Variable-temperature PXRD and TGA anal. experiments revealed considerable thermal stability of the supramol. framework of the Co^II complex. Magnetic studies showed that the distorted octahedral Co²⁺ ion exhibits considerable easy-plane magnetic anisotropy with D = 22.3 cm^-1, while field-induced single-ion magnet (SIM) behavior was evidenced at low temperature The forgoing results further highlight that the hydrogen-bonded supramol. framework could be used as a great platform for the development of mol. nanomagnets.

However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to azides. The presence of the three nitrogen atoms in triazole structures afforded opportunities for a plethora of structural modification with the generation of novel therapeutically potential agents, which is different from other heterocyclic compounds.Computed Properties of C9H7N3O2

A new polyhedron-based metal-organic framework (MOF), namely {[Co₆(OH)₂(H₂O)₄(cpt)₉](NO₃)(DMF)₁₃} (1, Hcpt = 4-(4′-carboxyphenyl)-1,2,4-triazole), was constructed by employment of a bifunctional triazolyl-carboxyl ligand Hcpt. Single crystal x-ray structural anal. shows that compound 1 features a rare hexanuclear {Co₆(OH)₂(H₂O)₆}¹⁰⁺ cluster and could be topol. viewed as a 10-connected bct net. Furthermore, compound 1 comprises octahedral cages with the inner diameter of 19.6 × 12.9 Ų and 2D pore systems along the a and b axis with high d. of open metal centers generated by the removal of coordinated water mols., which contribute to a high CO₂ adsorption capacity and significantly selective capture for CO₂ over CH₄ around room temperature In addition, the resulting activated 1a could behave as the heterogeneous Lewis catalyst facilitates the chem. fixation of CO₂ coupling with epoxides into cyclic carbonates under mind conditions.

Among the nitrogen-containing heterocyclic compounds, triazoles emerge with superior pharmacological applications. 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.Computed Properties of C9H7N3O2

Due to their large surface areas, tunable functionality, and diversiform building blocks, metal-organic frameworks (MOFs) have arisen great attention in the last few decades. Nevertheless, most of MOFs show poor water stability, which seriously hinders their further applications. In this study, through the immobilization of polyoxometalate in a water unstable cage-based MOF material {[(Cu₄Cl)(CPT)₄(H₂O)₄]·3NO₃·5NMP·3.5H₂O} (1), in which HCPT = 4-(4-carboxyphenyl)-1,2,4-triazole and NMP = N-Me pyrrolidone, via a simple one-pot solvothermal reaction, a new hybrid material {[(Cu₄Cl)(CPT)₄]·(HSiW₁₂O₄₀)·31H₂O} (2) can be fabricated. The hybrid material 2 shows a nearly identical network structure to that of 1 but possesses much higher water and chem. stability. Moreover, the visible light dye degradation performance for 2 in water has been illustrated.

And the article was included in Inorganic Chemistry in 2017.Application In Synthesis of 4-(4H-1,2,4-Triazol-4-yl)benzoic acid This article mentions the following:

Three organic ligands bearing 1,2,4-triazolyl donor moieties, (S)-4-(1-phenylpropyl)-1,2,4-triazole (trethbz), 4-(1,2,4-triazol-4-yl)benzoic acid (trPhCO₂H), and 3-(1H-imidazol-4-yl)-2-(1,2,4-triazol-4-yl)propionic acid (trhis), were prepared to evaluate their coordination behavior in the development of Mo(VI) oxide organic hybrids. Four compounds, [Mo₂O₆(trethbz)₂]·H₂O (1), [Mo₄O₁₂(trPhCO₂H)₂]·0.5H₂O (2a), [Mo₄O₁₂(trPhCO₂H)₂]·H₂O (2b), and [Mo₈O₂₅(trhis)₂(trhisH)₂]·2H₂O (3), were synthesized and characterized. The monofunctional tr-ligand gave a zigzag chain [Mo₂O₆(trethbz)₂] built up from cis-{MoO₄N₂} octahedra united through common μ₂-O vertexes. Employing the heterodonor ligand with tr/-CO₂H functions afforded either layer or ribbon structures of corner- or edge-sharing {MoO₅N} polyhedra (2a or 2b) stapled by tr-links in axial positions, whereas -CO₂H groups remained uncoordinated. The presence of the imidazole-heterocycle as an extra function in trhis facilitated formation of zwitterionic mols. with a protonated imidazolium group (imH⁺) and a neg. charged -CO₂^– group, whereas the tr-fragment was left neutral. Under the acidic hydrothermal conditions used, the organic ligand binds to Mo atoms either through [N-N]-tr or through both [N-N]-tr and μ₂-CO₂^– units, which occur in protonated bidentate or zwitterionic tetradentate forms (trhisH⁺ and trhis, resp.). This leads to a new zigzag subtopol. motif (3) of neg. charged polyoxomolybdate {Mo₈O₂₅}_n^2n- consisting of corner- and edge-sharing cis-{MoO₄N₂} and {MoO₆} octahedra, while the tetradentate zwitterionic trhis species connect these chains into a 2D net. Electronic spectra of the compounds showed optical gaps consistent with semiconducting behavior. The compounds were studied as epoxidation catalysts via the model reactions of achiral and prochiral olefins (cis-cyclooctene and trans-β-methylstyrene) with tert-Bu hydroperoxide. The best-performing catalyst (1) was explored for the epoxidation of other olefins, including biomass-derived Me oleate, Me linoleate, and prochiral DL-limonene. In the experiment, the researchers used many compounds, for example, 4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2Application In Synthesis of 4-(4H-1,2,4-Triazol-4-yl)benzoic acid).
