Red Phosphorescent Bis-Cyclometalated Iridium Complexes with Fluorine-, Phenyl-, and Fluorophenyl-Substituted 2-Arylquinoline Ligands

Red phosphorescent iridium(III) complexes based on fluorine-, phenyl-, and fluorophenyl-substituted 2-arylquinoline ligands were designed and synthesized. To investigate their electrophosphorescent properties, devices were fabricated with the following structure: indium tin oxide (ITO)/4,4′,4′′-tris[2-naphthyl(phenyl)amino]triphenylamine (2-TNATA)/4,4′-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (NPB)/4,4′-bis(N-carbazolyl)-1,1′-biphenyl (CBP): 8 % iridium (III) complexes/bathocuproine (BCP)/tris(8-hydroxyquinolinato)aluminum (Alq3)/8-hydroxyquinoline lithium (Liq)/Al. All devices, which use these materials showed efficient red emissions. In particular, a device exhibited a saturated red emission with a maximum luminance, external quantum efficiency, and luminous efficiency of 14200 cd m-2, 8.44 %, and 6.58 cd A-1 at 20 mA cm-2, respectively. The CIE (x, y) coordinates of this device are (0.67, 0.33) at 12.0 V. Dopant in red: Nine iridium complexes with fluorine-, phenyl-, and fluorophenyl-substituted 2-arylquinoline ligands for red phosphorescence organic light-emitting diodes were prepared. A device based on (2,4-pentanedionato)bis[2-(9,9-dimethyl-9 H-fluoren-2-yl)-5-(4-fluorophenyl)quinolinyl]iridium(III) showed an efficient deep red emission with an external quantum efficiency of 8.44 % at 20 mA cm-2.

Practical iron- and cobalt-catalyzed cross-coupling reactions between n-heterocyclic halides and aryl or heteroaryl magnesium reagents

The reaction scope of iron- and cobalt-catalyzed cross-coupling reactions in the presence of isoquinoline (quinoline) in the solvent mixture tBuOMe/THF has been further investigated. Various 2-halogenated pyridine, pyrimidine, and triazine derivatives were arylated under these mild conditions in excellent yields. The presence of isoquinoline allows us to perform Fe-catalyzed cross-coupling reactions between 6-chloroquinoline and aryl magnesium reagents. Furthermore, it was found that the use of 10% N,N-dimethylquinoline-8-amine increases the yields of some Co-catalyzed cross-coupling reactions with chloropyridines bearing electron-withdrawing substituents. Iron out your coupling! The use of iron and cobalt catalysts in a combination with only 10% isoquinoline represents a practical method for the cross-coupling reactions of various 2-halogenopyridines, -pyrimidines, and -triazines, as well as 6-halogenoquinolines with functionalized aryl or heteroaryl Grignard reagents (see scheme).
