Palladium-catalyzed desulfitative arylation of 3-haloquinolines with arylsulfinates
摘要:
3-Haloquinolines can be functionalized via a palladium-catalyzed desulfitative coupling of arylsulfinates. This method tolerates substitution upon the aromatic ring and shows good selectivity toward variously substituted aromatic rings. (C) 2013 Elsevier Ltd. All rights reserved.
An organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode and including an emission layer. The emission layer includes at least one doping layer and at least one non-doping layer. The doping layer comprises a first host, a second host, and a dopant.
