Improved luminance and external quantum efficiency of red and white organic light-emitting diodes with iridium(III) complexes with phenyl-substituted 2-phenylpyridine as a second cyclometalated ligand

Two novel red Ir(iii) complexes, (PQ)2Ir(Pppy) and (DMPQ)2Ir(Pppy), based on 2-phenylquinoline (PQ) and 2-(3,5-dimethylphenyl)quinoline (DMPQ) as cyclometalating ligands and 2-[4-(phenyl)phenyl]pyridine (Pppy) as a second cyclometalated ligand were synthesized for use in phosphorescent organic light-emitting diodes (OLEDs). The photoluminescence (PL) of (PQ)2Ir(Pppy) and (DMPQ)2Ir(Pppy) produces red emissions with maximum emission peaks at 602 and 615 nm, respectively. The highest occupied molecular orbital and lowest unoccupied molecular orbital energy levels of (PQ)2Ir(Pppy) and (DMPQ)2Ir(Pppy) were -5.15/-2.97 and -5.13/-2.96 eV, respectively. Red phosphorescent organic light-emitting devices were fabricated based on (PQ)2Ir(Pppy) or (DMPQ)2Ir(Pppy) as red dopants: ITO (50 nm)/PEDOT:PSS (40 nm)/NPB (20 nm)/TCTA (10 nm)/TCTA:TPBi:red dopant (25 nm, 10%)/TPBI (35 nm)/LiF (1 nm)/Al (200 nm). (PQ)2Ir(Pppy) and (DMPQ)2Ir(Pppy) exhibited a very broad full width at half maximum (FWHM) at around 100 nm in electroluminescent (EL) devices, which makes it suitable for fabricating white OLEDs with high colour quality. Among the these devices, the device fabricated by (DMPQ)2Ir(Pppy) of higher PL quantum yields (Φpl) than that of (PQ)2Ir(Pppy) showed an EL emission peak at 617 nm and a maximum external quantum efficiency (EQEmax) of 19.2%. Moreover, a white OLED prepared from (DMPQ)2Ir(Pppy) with FIrpic and Ir(ppy)3 gave the best performance, with an EQEmax of 21.9%, maximum power efficiency of 24.8 lm W-1, luminous efficiency of 40.2 cd A-1, and Commission Internationale de L'Eclairage coordinates of (0.39,0.41) at a luminance of 1000 cd m-2.

The iridium-mediated direct arylation of quinoline using an NHC ligand is reported. This reaction proceeds via cleavage of the carbon-carbon and carbon-nitrogen bonds of the NHC ligand and a carbon-hydrogen bond of quinoline.

Kinetic Resolution of 2,2-Disubstituted Dihydroquinolines through Chiral Phosphoric Acid-Catalyzed C6-Selective Asymmetric Halogenations

A novel kinetic resolution of 2,2-disubstituted dihydroquinolines was achieved by regioselective asymmetric halogenations enabled by chiral phosphoric acid catalysis. A series of dihydroquinolines bearing 2,2-disubstitutions were well-tolerated in these reactions, generating both the recovered dihydroquinolines and C-6-brominated products with high enantioselectivities, with s-factors up to 149. In addition, this kinetic resolution protocol is also applicable for 2,2-disubstituted tetrahydroquinoline and asymmetric iodonation reaction.

Preparation of 2-Arylquinolines from 2-Arylethyl Bromides and Aromatic Nitriles with Magnesium and N -Iodosuccinimide

Treatment of 2-arylethylmagnesium bromides, prepared from 2-arylethyl bromides and magnesium, with aromatic nitriles, followed by reaction with water and then with N -iodosuccinimide under irradiation with a tungsten lamp, gave the corresponding 2-arylquinolines in good to moderate yields under transition-metal-free conditions. 2-Alkylquinolines could be also obtained in moderate yields by the same procedure with 2-arylethyl bromides, magnesium, aliphatic nitriles bearing a secondary alkyl group, and N -iodosuccinimide.

Pd-Catalyzed Tandem Reaction of 2-Aminostyryl Nitriles with Arylboronic Acids: Synthesis of 2-Arylquinolines

A novel palladium-catalyzed protocol for the synthesis of 2-arylquinolines via tandem reaction of 2-aminostyryl nitriles with arylboronic acids has been developed with good functional group tolerance. The presented approach offers a new synthetic pathway toward the core structures of 2-arylquinolines compared to classical condensation reaction of (E)-2-aminostyryl aryl ketones. Moreover, the present synthetic route could be readily scaled up to gram quantity without difficulty. Preliminary mechanistic experiments showed that this transformation involves a nucleophilic addition of aryl palladium species to the nitrile to generate an aryl ketone intermediate followed by an intramolecular cyclization and dehydration to quinoline ring.
