HPLC of Formula: 5805-39-0In 2019, Hu, Wangqin;Yang, Wen;Gong, Tingfeng;Zhou, Weiqun;Zhang, Yuhan published 《Multi-stimuli responsive properties switch by intra- and inter-molecular charge transfer constructed from triphenylamine derivative》. 《CrystEngComm》published the findings. The article contains the following contents:
Combining triphenylamine (TPA) and 2-(1H-benzo[d]imidazol-2-yl) aniline (BI), a typical fluorescent dye, TPA-BI, was designed and synthesized. The photo-phys. properties of this compound were investigated both in solution and the solid state. TPA-BI showed a strong AIEE effect and its relative fluorescence quantum yield (φf) was up to 63.4% in the aggregation state. The tunable fluorescence phenomenon by the MCF effect was observed between the amorphous (bluish violet) and crystalline (green) states, and the absolute φf was determined to be 56.2% and 21.9%, resp., by the integral sphere method. Meanwhile, pH titration experiments exhibited the tunable fluorescence phenomenon in different pH solutions Thus, TPA-BI could also be used as a fluorescent switch from green to bluish-violet based on its response to volatile acidic and alk. organic compounds in the solid state repeatedly without fatigue and destruction under UV illumination (365 nm), which can be explained by the reversible transformation by protonation and deprotonation. The protonation process was further confirmed in detail by 1HNMR titration experiments D. functional theory (DFT) and time-dependent d. functional theory (TD-DFT) were used to predict the multi-stimuli responsive fluorescence properties. And 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) was used in the research process.
2-(1H-Benzo[d]imidazol-2-yl)aniline(cas:5805-39-0 HPLC of Formula: 5805-39-0) 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.
