Paragraph 0405; 0409, (2020/11/22)
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, the organic layer including an emission layer. The emission layer includes at least one organometallic compound of Formula 1, and at least one selected from a second compound and a third compound, where the organometallic compound, the second compound, and the third compound are different from each other. When the emission layer comprises both the second compound and the third compound, the second compound and the third compound form an exciplex, and the organometallic compound and the second compound and/or the third compound do not form an exciplex: [in-line-formulae]M(L1)n1(L2)n2,??Formula 1[/in-line-formulae] wherein in Formula 1, L1 is represented by Formula 2-1:

Azidopyrazines do not undergo reduction by reagents that are effective for the preparation of alkyl- or arylamines from the azides because the heterocyclic azides exist in the bicyclic form of tetrazolo[1,5-a]pyrazines. Nevertheless, the conversion into aminopyrazines was achieved by hydrogenolysis in the presence of ammonium hydroxide and palladium-on-carbon or particularly by reduction with tin(II) chloride in methanolic hydrochloric acid, in 34-87% yields. To elucidate the successful progress of the reaction, the equilibrium of azide-atetrazole was examined by 1H NMR spectroscopy in various solvents.
