Research speed reading in 2021. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. 75178-96-0, Name is tert-Butyl (3-aminopropyl)carbamate, molecular formula is , belongs to benzoxazole compound. In a document, author is Weng, Qiang, Category: benzoxazole.
Modifying the position and numbers of lateral fluorine substituent is a common method to design and adjust the mesophase of liquid crystal compounds. Here, a series of 2-(2,2′-difluoro-4′-alkoxy-1,1′-biphenyl-4-yl)-5-substituted benzoxazole with both non-polar (H, CH3) and polar (NO2) groups (coded as nPF(2)PF(2)Bx) is synthesised and characterised. All of the compounds show a conspicuous inter-ring twist angle of 38 degrees compared with corresponding reference compounds I and II which are calculated by density functional theory method, and it is interesting to note that the final compounds nPF(2)PF(2)Bx show only nematic mesophase during heating or cooling. Meanwhile, the UV-vis absorption bands and photoluminescence emission peaks both display remarkable blue-shifted. The aforementioned results reveal that lateral difluoro substituents play a key role to stable the nematic mesophase by increasing the dihedral angle of biphenyl.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 75178-96-0, you can contact me at any time and look forward to more communication. Category: benzoxazole.
