And the article was published in Polymer Degradation and Stability in 2019. Computed Properties of C7H7N3 The author mentioned the following in the article:

A flame-retardant curing agent (DTA) for epoxy resin (EP), which was constructed by phosphaphenanthrene and benzimidazole groups, was successfully synthesized via one-pot reaction between 2-aminobenzimidazole, terephthalaldehyde, and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). DTA induced the decomposition of EP matrix and promoted the carbonization at high temperature As expected, DTA endowed EP thermoset with excellent flame retardancy and smoke suppression. For instance, EP/DDS/DTA-0.5 sample containing only 0.5 wt% phosphorus passed UL94 V-1 rating and its LOI value increased to 34.2%. In addition, the pk-HRR, av-HRR, THR, TSR, and TSP of EP/DDS/DTA-1.0 sample were decreased by 56.6%, 31.6%, 34.4%, 24.6% and 24.6% in comparison to those of EP/DDS sample. The flame retardant mechanism showed that the decomposition products of DTA played an important role in the formation of a compact and intumescent char layer in condensed phase. Meanwhile, the phosphorus-containing and nitrogen-containing fragments, which was generated by the pyrolysis of DTA, quenched the active free radicals and diluted the fuels in gaseous phase. Therefore, DTA exerted flame retardant effect in condensed and gaseous phases during combustion. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Computed Properties of C7H7N3)

Synthesis of Co(II), Cu(II) and Zn(II) complexes of bidentate Schiff base ligand (L) 2-(1H-Benzo [d]imidazole-4-ylimmino) Me phenol is presented here. The Schiff base and its metal (II) complexes were characterized by micro anal. and spectral techniques such as AAS, UV-visible, FTIR, NMR, molar conductance and magnetic moment measurements. Molar conductance reveals the non electrolytic nature of the complexes. From the anal. and spectral anal., octahedral geometry is proposed to the synthesized metal (II) complexes. DFT calculations were done for Schiff base and metal (II) complexes to confirm the geometry of the complexes. The sensor activity of Schiff base towards calcium and magnesium ions was studied by absorption spectroscopy. Electrochem. nature of the copper(II) complex was studied by cyclic voltammetry technique and indicates the reversible nature of Cu(II)/Cu(I) couple. The antimicrobial activity of the Schiff base and its metal (II) complexes showed good potency against various microorganism such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans. DNA binding properties of the metal complexes were studied using UV-visible absorption spectroscopy and found that the Cu(II) complex has more binding ability than L, Co(II) and Zn(II) complexes.

The article was titled 《Immobilization of copper(II) into polyacrylonitrile fiber toward efficient and recyclable catalyst in Chan-Lam coupling reactions》.Application In Synthesis of 1H-Benzo[d]imidazol-2-amine The article contains the following contents:

A series of polyacrylonitrile fiber (PANF)-supported copper(II) catalysts were prepared through the immobilization of Cu(II) into prolinamide-modified PANF (PANPA-2F) and subsequently used for the synthesis of diverse N-arylimidazoles from arylboronic acids and imidazole. The prepared Cu(II)@PANPA-2Fs were well characterized by mech. strength, FT-IR, XRD, XPS and SEM. Among them, CuCl2@PANPA-2F exhibited excellent catalytic performance and its activity was significantly affected by the Cu loading. This catalytic system also displayed good activity in the synthesis of N-arylsulfonamides from arylboronic acids and tosyl azide. The catalyst was highly efficient in gram-scale reactions and could be reused five times. The advantages of low cost, easy preparation, good durability, and facile recovery made the fiber catalyst attractive.

《Cyclic Voltammetry as an Electroanalytical Tool for Analysing the Reaction Mechanisms of Copper in Chloride Solution Containing Different Azole Compounds》 was published in Current Analytical Chemistry in 2020. These research results belong to Finsgar, Matjaz; Xhanari, Klodian; Curkovic, Helena O.. Electric Literature of C7H7N3 The article mentions the following:

Cyclic voltammetry is widely employed in electroanal.studies because it provides fast information about the redox potentials of the electroactive species and the influence of the medium on the redox processes. Azole compoundshave been found to be effective corrosion inhibitors for copper in chloride-containingsolutions The aim of this work was to investigate in detail the influence of the addition of various azole compoundson the oxidationmechanism of copper in chloride-containingsolutions, using cyclic voltammetry. The influence of thirteen azole compounds, at three different concentrationson the electrochem./ chem. reactions of pure copper immersed in 3 weight% NaCl solutionwas studied using cyclic voltammetry at different scan rates. The change of the peak current and potential with the scan rate were investigated. The possible linearity was compared with the theor.derived mechanism. The possible reaction mechanisms were discussed based on the linearity of these parameters (peak current and potential) with the scan rate compared to theor.derived models. Both the peak current and peak potential of the copper samples immersed in chloridecontaining solutionswith additionsof the majority of azole compoundsshowed linearity with the square root of the scan rate, suggesting that copper follows the Muller-Calandra passivation model. The same behavior was also found for copper in chloride-containing solutions without additionsof azole compounds A linear variation of the peak potential with the natural logarithm of the scan rate and linear variation of the peak potential with the square root of the scan rate was observed for the copper samples immersed in chloride-containing solutions with the addition of 10 mM of 2-mercapto-1- methylimidazole, imidazole, or 2-aminobenzimidazole. This suggests that copper follows irreversible redox reactions under a diffusion controlled process. No other linear relations of the peak current and peak potential with the scan rate were found. Copper oxidationin chloride-containingsolutionsis controlled by passivation (following the Muller-Calandra passivation model) upon the addition of the majority of the selected azoles. In the minority of cases, irreversible redox reactions that follow a diffusion-controlled process were identified. None of the systems followed an adsorption-controlled process. Moreover, none of the tested systems underwent reversible redox reactions that followed a diffusion controlled process. In the part of experimental materials, we found many familiar compounds, such as 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Electric Literature of C7H7N3)

《Functionalized ZIF-7/Pebax 2533 mixed matrix membranes for CO2/N2 separation》 was written by Gao, Jie; Mao, Haizhuo; Jin, Hua; Chen, Chen; Feldhoff, Armin; Li, Yanshuo. Category: imidazoles-derivativesThis research focused onzeolite mixed matrix membrane carbon dioxide nitrogen separation. The article conveys some information:

Membrane-based separation technol. has evolved as a competitive approach for CO2 capture from flue gas (mainly N2). To achieve high separation performance, three partially NH2-, OH- and CH3OH- functionalized mixed-linker-ZIF-7 were successfully synthesized, and incorporated into polyether-block-amide (Pebax 2533) polymer to form mixed-matrix membranes (MMMs). As evidenced by the CO2 adsorption isotherms, introducing functional groups in the ZIF-7 framework was indeed beneficial for CO2 adsorption. All MMMs composed of ZIF-7-NH2, ZIF-7-OH and ZIF-7-CH3OH offered better CO2/N2 separation performance than the parent ZIF-7-Pebax 2533 membrane, suggesting the pos. effect of functionalized ZIF-7 fillers on the gas separation performance. Among the three functionalized ZIF-7 based MMMs, the ZIF-7-OH-Pebax MMMs exhibited the best performance for CO2/N2 separation, which might be ascribed to the highest adsorption selectivity of CO2 over N2 predicted by ideal adsorbed solution theory (IAST) for ZIF-7-OH fillers. The 14% ZIF-7-OH-Pebax MMM showed high CO2 permeability of 273 Barrer and CO2/N2 separation factor of 38, which increased by 60% and 145% as compared with the neat Pebax membrane. The strategy of preparing functionalized MOFs with strong affinity for CO2 provides an effective method to develop MMMs for highly efficient CO2 separation In the experiment, the researchers used 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Category: imidazoles-derivatives)
