Let¡¯s face it, organic chemistry can seem difficult to learn. 22013-33-8. Especially from a beginner¡¯s point of view. Like 22013-33-8, Name is 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine. In a document type is Article, introducing its new discovery.
A series of efficient electroluminescent materials with dual carrier transport properties shows enhanced singlet exciton utilization (etas) due to small singlet-triplet splitting (DeltaEST). The strong orbital-coupling transitions of N-(4-(1-(1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-4,5-diphenyl-1H-imidazol-2-yl)naphthalen-4-yl)phenyl)-N-phenyl benzenamine (DDPB) exhibit deep blue emission at 435 nm (CIEy, 0.07) with an external quantum efficiency of 2.01%. The electroluminescent efficiencies of 2-(1-(9H-carbazol-9-yl)naphthalen-4-yl)-1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-1H-phenanthro[9,10-d]imidazole (CDDPI) (L-3992 cd m-2; etaex-3.01%; etac-2.56 cd A-1; etap-2.12 lm W-1) are higher than those of the N-(4-(1-(1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-H-phenanthro[9,10-d]imidazole-2-yl)naphthalen-4-yl)phenyl)-N-phenylbenzenamine (DBDPA) based device (L-3015 cd m-2; etaex-2.85%; etac-2.01 cd A-1; etap-1.92 lm W-1). The blue emissive materials CDDPI and DBDPA are used as a host to construct green and red phosphorescent OLEDs: the green device based on CDDPI:Ir(ppy)3 exhibits higher efficiencies (L-8812 cd m-2; etaex-19.0%; etac-27.5 cd A-1; etap-33.0 lm W-1) at 2.7 V and the red device based on CDDPI:Ir(MQ)2(acac) exhibits a maximum luminance of 39661 cd m-2 with excellent EL efficiencies [etaex-19.2%; etac-27.9 cd A-1; etap-29.2 lm W-1; CIE (0.64, 0.34)] compared with those of the DBDPA:Ir(MQ)2(acac) based device [L-37 621 cd m-2; etaex-18.5%; etac-25.2 cd A-1; etap-25.8 lm W-1; CIE (0.64, 0.34)].
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 22013-33-8, and how the biochemistry of the body works.22013-33-8
