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 (CIExy: 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 (CIExy: 0.32, 0.38), in methanol (CIExy: 0.32, 0.39), and in DMF (CIExy: 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) .
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.
