Copper-Catalyzed N,N-Diarylation of Amides for the Construction of 9,10-Dihydroacridine Structure and Applications in the Synthesis of Diverse Nitrogen-Embedded Polyacenes

We reported herein CuI/DMEDA catalyzed N,N-diarylation reaction of amides with various di(o-bromoaryl)methanes to produce diverse 9,10-dihydroacridine derivatives. The resulting 9,10-dihydroacridine derivatives were oxidized selectively under mild conditions to afford acridine, acridinone, and acridinium derivatives. The copper-catalyzed N,N-diarylation reaction coupled with oxidative aromatization reaction enabled the facile construction of nitrogen atom-embedded tetracenes and pentacenes of different ortho-fused patterns. The luminescence properties, especially the effect of fusion pattern on fluorescence emission of acquired N-polycenes, were also demonstrated.

A kind of metal complex and in the organic electroluminescent device in the application

The invention relates to a novel metal complex and application thereof in an organic luminescent device. The structural general formula of the metal iridium complex for near infrared luminescence is LnIrX(3-n), wherein X is selected from acetylacetone, dibenzoylmethane, dipivaloylmethane or picolinic acid; n is selected from 1, 2 or 3; L is selected from the following structural formula L1, L2 or L3; R1-R9 are independently selected from H, C1-10 alkyl, C1-10 alkoxy, C1-10 alkylamino, carbazolyl, F, trifluoromethyl and C5-18 aryl respectively; and Ar represents C5-18 aryl and C5-18 heterocyclic aryl. The metal complex has the advantages of short luminescence life and high luminescence efficiency; and an organic luminescent device prepared from the luminescent material has the characteristic of high luminescence efficiency under high current density. The structural formula L1, the structural formula L2 and the structural formula L3 are shown in the specification.
