New discoveries in chemical research and development in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 1895-39-2, Name is Sodium 2-chloro-2,2-difluoroacetate, molecular formula is C2ClF2NaO2. In an article, author is Luo, Li-Juan,once mentioned of 1895-39-2, Formula: https://www.ambeed.com/products/1895-39-2.html.
We have recently reported a strongly luminescent osmium(VI) nitrido complex [Os-VI(N)(NO2-L)(CN)(3)](-) [HNO2-L = 2-(2-hydroxy-5-nitrophenyl)benzoxazole]. The excited state of this complex readily activates the strong C-H bonds of alkanes and arenes (Commun. Chem. 2019, 2, 40). In this work, we attempted to tune the excited-state properties of this complex by introducing various substituents on the bidentate L ligand. The series of nitrido complexes were characterized by IR, UV/vis, H-1 NMR, and electrospray ionization mass spectrometry. The molecular structures of five of the nitrido compounds have been determined by X-ray crystallography. The photophysical and electrochemical properties of these complexes have been investigated. The luminescence of these nitrido complexes in the solid state, in a CH2Cl2 solution, and in a CH2Cl2 solid matrix at 77 K glassy medium clearly shows that these emissions are due to (LML)-L-3’CT [L ligand to Os (math)N] phosphorescence. The presence of strongly electron-withdrawing substituents in these complexes enhances the LML’CT emission. Our result demonstrates that the excited-state properties of this novel class of luminescent osmium(VI) nitrido complexes can be fine-tuned by introducing various substituents on the bidentate L ligand.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 1895-39-2. Formula: https://www.ambeed.com/products/1895-39-2.html.
