Name: 2-(1H-Benzo[d]imidazol-2-yl)aniline《Spectroscopic evaluation of a novel multi-element sensitive fluorescent probe derived from 2-(2′-phenylbenzamide)benzimidazole: Selective discrimination of Al3 + and Cd2 + from their congeners》 was published in 2016. The authors were Dhaka, Gargi;Kaur, Navneet;Singh, Jasvinder, and the article was included in《Inorganic Chemistry Communications》. The author mentioned the following in the article:
A novel fluorescent chemosensor 2-(2′-phenylbenzamide)benzimidazole (2) exhibiting excited-state intramol. proton transfer (ESIPT) process was synthesized by condensation approach, among which 2 could be used as a multielement sensitive fluorescent probe for both Al3 + and Cd2 +. The emission wavelength of 2 underwent blue shift of 78 nm upon binding with these ions. The cation-induced inhibition of ESIPT phenomenon was responsible for these fluorescence changes. Also, the absorption spectra of 2 showed changes with F– and AcO– ions also. TD-DFT studies well displayed the blue shift in the emission wavelength of 2 upon binding with Al3 + ions. To complete the study, the researchers used 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) .
2-(1H-Benzo[d]imidazol-2-yl)aniline(cas:5805-39-0 Name: 2-(1H-Benzo[d]imidazol-2-yl)aniline) is a chemical reagent used in the synthesis of small molecule inhibitors targeting ubiquitin-like domains for treatments of diseases caused by the cellular accumulation of damaged proteins.
