Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4) belongs to quinoxaline derivatives. Quinoxalines have received a significant amount of attention due to their potential use in fighting various pathophysiological conditions like epilepsy, Parkinson鈥檚, and Alzheimer鈥檚 diseases. Quinoxaline-1,4-di-N-oxide derivatives have shown to improve the biological results and are endowed with anti-viral, anti-cancer, anti-bacterial, and anti-protozoal activities with application in many other therapeutic areas.Name: Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile

Understanding the Origin of Degradation of InP-Quantum Dot Light-Emitting Diodes was written by Shin, Dong Hyun;Lampande, Raju;Kim, Su Jeong;Jung, Young Hun;Kwon, Jang Hyuk. And the article was included in Advanced Electronic Materials in 2022.Name: Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile This article mentions the following:

The origin of degradation of InP-QLED (quantum dot LED) is reported by comparing the stability of Cd-QDs and organic Bebq2:Ir(mphmq)2(tmd) emissive layers (EMLs). The degradation causes of InP-QLED are checked by measuring the stability of hole and electron only devices (HOD and EOD) against hole/electron, exciton stress, and hole/electron-exciton stress conditions. The results show that the InP-QDs layer is more vulnerable to exciton and electron-exciton stress compared to the Cd-QDs and Bebq2:Ir(mphmq)2(tmd) due to the increase of surface defects in the InP-QDs after exciton and electron-exciton stress, which increases non-radiative Auger recombination process. However, InP-QDs are relatively less stable against electron and hole stress than the Cd-QDs and Bebq2:Ir(mphmq)2(tmd). To reduce the electron-exciton stress on the InP-QDs, an inverted red QLED with InP-QDs:DBTA EML is fabricated. The QLED with InP-QDs: hole transport layer (DBTA) shows a low driving voltage of 5.7 V, high external quantum efficiency (EQE) of 10.2%, and longer lifetime (T50:557 h at 1000 cd m-2) than the reference InP-QDs device (T50: 29 h at 1000 cd m-2). In the experiment, the researchers used many compounds, for example, Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4Name: Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile).
