Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4) belongs to quinoxaline derivatives. Condensed heterocycles of quinoxalines have become attractive targets in synthetic and medicinal chemistry due to their significant biological activities. Quinoxaline and its analogues may also be formed by reduction of amino acids substituted 1,5-difluoro-2,4-dinitrobenzene (DFDNB),One study used 2-iodoxybenzoic acid (IBX) as a catalyst in the reaction of benzil with 1,2-diaminobenzene.COA of Formula: C18N12

Lateral current suppression in tandem organic light-emitting diodes by adopting a buffer layer was written by Wang, Jiong;Zhang, Yaqi;Wang, Ruiting;Wang, Yangcheng;Zhang, Fangbo;Chen, Yuehua;Lou, Hui;Lai, Wenyong;Zhang, Xinwen;Huang, Wei. And the article was included in Organic Electronics in 2022.COA of Formula: C18N12 This article mentions the following:

For the tandem organic light emitting diodes (TOLEDs) with the charge generation unit (CGU) of LiF/Al/MoO3, there is a significant current lateral spreading causing light emission over an extremely large area outside the OLEDs pixel, due to the conductive interfacial layer caused by the oxidation-reduction reaction between Al and MoO3 layers. To crack this nut, a buffer layer of 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HAT-CN) is inserted between Al and MoO3 layers. The result shows the HAT-CN buffer layer eliminates the spread light emission in the TOLEDs. What’s more, the device characteristics show the new CGU of LiF/Al/HAT-CN/MoO3 has stronger charge generation and injection capabilities. The white TOLEDs with the new CGU exhibit a high external quantum efficiency (EQE) of 28.4%. Compared with the single OLEDs and the TOLEDs with the CGU of LiF/Al/MoO3, the efficiency is increased by 143% and 44%, resp. 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: 105598-27-4COA of Formula: C18N12).
