The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.3939-23-9, Name is 3-Bromo-10H-phenothiazine, molecular formula is C12H8BrNS, 3939-23-9. In a Article, authors is Su, Sheng-Yuan£¬once mentioned of 3939-23-9
Dual optical responses of phenothiazine derivatives: Near-IR chromophore and water-soluble fluorescent organic nanoparticles
We have designed a conventional one-step organic coupling synthetic method to prepare a series of 10H-phenothiazine (PTZ) derivative fluorophores and investigated their optical behavior under alkaline conditions. The unexpected proton detachment at N-10 position (10N-H) of these PTZ derivatives provides switching between the visible fluorophore and near infrared (NIR) chromophore. Both anionic forms of compounds PTZ-NH and PTZ-OH exhibit strong red emission in alkali DMSO solutions, whereas only anionic PTZ-OH exhibits the near infrared absorption wavelength at 1010 nm. Moreover, the unexpected green fluorescence is observed due to the formation of fluorescent organic nanoparticles (FONs) when PTZ-OH is dissolved in alkaline aqueous conditions. These results indicate that these compounds have the potential for use in alkaline sensor applications, especially in aqueous solution.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.3939-23-9. In my other articles, you can also check out more blogs about 3939-23-9
