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. The parent substance of the group, quinoxaline, results when glyoxal is condensed with 1,2-diaminobenzene. Substituted derivatives arise when 伪-ketonic acids, 伪-chlorketones, 伪-aldehyde alcohols and 伪-ketone alcohols are used in place of diketones.Quality Control of Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile

Dual role of novel hole-transporting and deep-blue emitting materials based on twisted binaphthyl was written by Huang, Haifang;Kong, Yafen;Gao, Jian;Fan, Heliang;Lin, Qifu. And the article was included in Optical Materials (Amsterdam, Netherlands) in 2022.Quality Control of Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile This article mentions the following:

Three novel deep blue-emitting materials from binaphthyl derivatives, namely BFS, BNS and BNF, were designed and synthesized. Due to their rigid structure, all the materials exhibit high thermal stability with Td exceed 440 掳C and Tg as high as 153 掳C, 149 掳C and 140 掳C, resp. They also show appropriate HOMO and LUMO energy level, excellent amorphous stability and outstanding solubility in common organic solvents. These novel materials are highly emissive in both solution and solid states, with deep blue emissions peaked at 鈭?50 nm. Deep-blue OLEDs using the novel materials as emitter resulted in efficient CE, EQE and luminance. The BFS, BNS and BNF based devices show good EL performances with the Lmax of 857 cd/m2 (CEmax of 0.3 cd/A), Lmax of 1038 cd/m2 (CEmax of 0.5 cd/A), and Lmax of 3717 cd/m2 (CEmax of 0.5 cd/A), resp. They should be promising hole-transport and deep blue-emitting materials for OLED devices. 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: 105598-27-4Quality Control of Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile).
