Abstract
- Upon fusing the pyrazinyl pyrazole entity in giving pyrazolo[3,4‐f]quinoxaline chelate, the corresponding Os(II) based NIR emitter exhibited "invisible" and efficient electroluminescence with a peak maximum at 811 nm. A maximum external quantum efficiency of 0.97 % and a suppressed efficiency roll‐off till a current density of 300 mA cm−2 was also exhibited. [ABSTRACT FROM AUTHOR]
