Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Verbitskiy, Egor V., once mentioned the application of 123-32-0, Name is 2,5-Dimethylpyrazine, molecular formula is C6H8N2, molecular weight is 108.14, MDL number is MFCD00006147, category is Pyrazines. Now introduce a scientific discovery about this category, COA of Formula: C6H8N2.
The effect of molecular structure on the efficiency of 1,4-diazine-based D-(pi)-A push-pull systems for non-doped OLED applications
A series of novel D-A and D-pi-A push-pull systems based on a pyrazine and quinoxaline acceptor, bearing various electron-donating triphenylamine and carbazole moieties, are compared. A significant difference in electrochemical and photophysical properties was found depending on molecular structure. The compounds have strong solvatochmmic properties. Quinoxaline-containing systems exhibit delayed fluorescence (DF) in thermal vacuum deposition films. Despite the low quantum yield of fluorescence in the solid state (less than 10%), organic light-emitting diodes with sufficiently high efficiency (4.2 cd/A) have been fabricated on the basis of this push-pull systems. The best results were obtained for compounds exhibiting DF. The possible channel for increasing the efficiency of OLED can be associated with the hot excitons mechanism.
