Paragraph 0079; 0080, (2018/01/05)
The invention discloses a polysubstituted quinoline-coordinated iridium-hybridized compound, a preparation method thereof and application of the compound in electroluminescent materials. A modified ligand of the compound comprises 3,5-bis-substituted(R R) in 2-subsittued phenyl, 4-substituted(R) and 3,4,5-tri-substituted(R R R)phenyl. The specific synthesis route of the polysubstituted quinoline-coordinated iridium-hybridized compound comprises the steps of generating substituted quinoline by virtue of amine ester exchange reaction, acid-catalysis Skraup cyclocondensation and hydroxyl halogenating reaction, and preparing ligand by virtue of Suzuki coupling reaction. According to the route, the side reactions of alkyl suzuki coupling reaction and competition of multiple reaction sites are avoided, so that the synthesis efficiency can be improved, and the purifying difficulty can be reduced. According to molecular spectral features and compound modification functions, the iridium-hybridized compound can be clearly used as an electroluminescent material for use in organic photoelectric appliances.

N-Arylaroylacetamides and 4-aryl-1,5-benzodiazepin-4-ones were obtained by the thermolysis of 2,2-dimethyl-6-aryl-1,3-dioxin-4-ones in the presence of aromatic amines and o-phenylenediamine respectively.Investigetion of the reaction kinetics showed that the controlling stage is the generation of the aroylketenes, which takes place by a concerted -retrocycloaddition mechanism.
