Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 52409-22-0, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 52409-22-0
Four novel molecules, 9-(9,10-diphenylanthracen-3-yl)-9H-carbazole (1), 7-(9,10-diphenylanthracen-3-yl)-7H-benzo[c]carbazole (2), 7-(9,10-diphenylanthracen-3-yl)-7H-benzo[e]pyrido[3,2-b]indole (3), 7-(9,10-diphenyl-2-(7H-benzo[e]pyrido[3,2-b]indol-7-yl)anthracen-6-yl)-7H-benzo[e]pyrido[3,2-b]indole (4), based on 9,10-diphenylanthracene with carbazole derivatives, were designed and synthesized via Buchwald-Hartwig cross-coupling reactions. Multilayer OLED devices were fabricated with the following device structure: ITO/2-TNATA (60 nm)/NPB (20 nm)/alpha,beta-ADN:blue dopant materials (10%, 30 nm)/DNAB (30 nm)/Liq:Al. Among those, the device using 1 exhibited the efficient blue emission with a luminous efficiency of 4.56 cd/A, power efficiency of 1.95 lm/W, an external quantum efficiency of 3.42%, and CIE x,y coordinates of (0.15, 0.17) at 20 mA/cm2, respectively.
