Category: imidazoles-derivativesIn 2019, Li, Jia-Bin;Liu, Yang;Zheng, Xiang-Jun;Wang, Dan published 《An off-on chemosensor for Hg2+ based on the excimer emission of anthracene》. 《Microchemical Journal》published the findings. The article contains the following contents:
A quinazoline derivative 6-anthracenyl-5,6-2H-benzimidazo[1,2-c]quinazoline (L) was obtained and characterized by elemental anal., IR spectroscopy, 1H NMR and single-crystal X-ray diffraction. L shows very weak emission in DMSO, but can respond to Hg2+ ion intensively in off-on mode. Job’s plot and titration experiments show that Hg2+ ion binds L in 1:1 stoichiometry. The detection limit for Hg2+ is 6.34μM. 1H NMR titration experiments indicate that only one benzimidazo nitrogen atom coordinates with Hg2+. And the fluorescence emission spectra imply that an excimer formed in the Hg2+-L system, and the detection of Hg2+ was realized by excimer emission of anthracene moiety. The experimental procedure involved many compounds, such as 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) .
2-(1H-Benzo[d]imidazol-2-yl)aniline(cas:5805-39-0 Category: imidazoles-derivatives) 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.
