A simple and efficient strategy for the derivatization at the 2- and 3- positions in fluorene unit was explored. By introducing different types of substituents, 2 pairs of 2,3-disubstituted fluorene isomers were designed and used as host materials for phosphorescent organic light-emitting diodes (PHOLEDs). The green PHOLEDs hosted by these fluorene derivatives realize high external quantum efficiencies (EQE) >20% with low efficiency roll-off. The devices hosted by 2TRz3TPA and 2TPA3TRz achieve nearly 24% EQE and 104 lm W-1 power efficiency. The 2,3-disubstituted fluorene platforms are potentially useful for constructing host materials. 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: 105598-27-4Related Products of 105598-27-4).
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-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.Related Products of 105598-27-4
