Khan, Salman A.;Ullah, Qasim;Parveen, Humaira;Mukhtar, Sayeed;Alzahrani, Khalid Ahmed;Asad, Mohammad published 《Synthesis and photophysical investigation of novel imidazole derivative an efficient multimodal chemosensor for Cu(II) and fluoride ions》. The research results were published in《Journal of Photochemistry and Photobiology, A: Chemistry》 in 2021.SDS of cas: 5805-39-0 The article conveys some information:

Aminophenylbenzimidazole derivative of theonyl trifluoro acetone has been designed, synthesized and characterized to sense Cu(II) and fluoride ions. The probe showed very selective colorimetric and ratiometric fluorescence changes with copper(II), turn-on fluorescence behavior with fluoride ions. ESI-MS anal. and jobs plots anal. provided the information about the interaction mode between Cu(II) and the probe. D. functional theory calculations carried out on the probe with/without Cu(II) and fluoride ions to support the observed photophys. changes. The Probe can be utilized to detect Cu(II) ions via electrochem. detection and hence it can be used to detect copper ions by multiple modes. The fluorescence and absorbance change with fluoride ions showing that the probe is very sensitive towards fluoride ions among other anions. The detection limits for the detection of Cu(II) and fluoride ions were found to be 23 nM and 0.54 nM resp. To complete the study, the researchers used 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) .

Name: 2-(1H-Benzo[d]imidazol-2-yl)anilineIn 2021, Li, Jia-Bin;Zheng, Han-Wen;Wu, Min;Liang, Qiong-Fang;Yang, Dong-Dong;Zheng, Xiang-Jun;Tan, Hong-Wei published 《Multistimulus Response of Two Tautomeric Zn(II) Complexes and Their White-Light Emission Based on Different Mechanisms》. 《Inorganic Chemistry》published the findings. The article contains the following contents:

A triphenylamine (TPA)-based 2H-quinazoline Zn(II) complex (Q-TPA-Zn) exhibiting dual fluorescence and phosphorescence emission in the solid state was designed and prepared It possesses mechanochromic luminescence and thermochromic luminescence properties. In the solid state, the white afterglow luminescence could be observed at 77 K (CIE_xy: 0.27, 0.33) while cyan luminescence could be observed at 297 K. After thermolysis at 300 °C, Q-TPA-Zn could be transformed into Schiff base complex S-TPA-Zn with white fluorescence in the powder state (CIE_xy: 0.32, 0.38), in methanol (CIE_xy: 0.32, 0.39), and in DMF (CIE_xy: 0.26, 0.32) at room temperature This arises from dual emission of normal* emission and tautomeric* emission induced by excited-state intramol. proton transfer (ESIPT) from the benzimidazole NH group to the Schiff base N atom. Q-TPA-Zn could also be transformed into its isomeric form, S-TPA-Zn, through photochem. ring-opening reaction upon irradiation under 365 nm in the solution, exhibiting high-contrast photochromic luminescence. Interestingly, S-TPA-Zn could further be transformed into its zwitterionic isomer after continuous irradiation The same ring-opening reaction could also take place for the organic compound Q-TPA via heating or 365 nm irradiation The ring-opening reaction mechanism and ESIPT emission were interpreted via theor. calculation To complete the study, the researchers used 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) .

Product Details of 5805-39-0《Microwave Assisted Green Synthesis of Benzimidazole Derivatives and Evaluation of Their Anticonvulsant Activity》 was published in 2019. The authors were Sahoo, Biswa Mohan;Banik, Bimal Krishna;Mazaharunnisa;Rao, Naidu Srinivasa;Raju, Bodapati, and the article was included in《Current Microwave Chemistry》. The author mentioned the following in the article:

N-(Benzimidazolylphenyl)cinnamides I (R = Ph, 2-ClC₆H₄, 4-ClC₆H₄, 4-FC₆H₄, 4-HC₆H₄) are synthesized by reaction between ortho-phenylene diamine and anthranilic acid followed by acetylation in the presence of acetic anhydride and Claisen-Schmidt condensation with substituted benzaldehydes RCHO. Both conventional and microwave irradiation technol. are followed to get the titled compounds I. The titled compounds are screened for their anticonvulsant activity and neurotoxicity. By the help of microwave synthesis, the yield of product was increased in less reaction time. So, it follows Green chem. approach by making above reactions eco-friendly. Some of the compounds exhibited significant anticonvulsant activity as compared to standard drug. And 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) was used in the research process.
