The strong orbital-coupling transitions of -(4-(1-(1-(2,3-dihydrobenzo[][1,4]dioxin-6-yl)-4,5-diphenyl-1-imidazol-2-yl)naphthalen-4-yl)phenyl)--phenyl benzenamine (DDPB) exhibit deep blue emission at 435 nm (CIEy, 0.07) with an external quantum efficiency of 2.

Hot exciton transition for organic light-emitting diodes: tailoring excited-state properties and electroluminescence performances of donor-spacer-acceptor molecules.

The photophysical, electrochemical and electroluminescent properties of newly synthesized blue emitters with donor-π-acceptor geometry, namely, 4'-(1-(naphthalen-1-yl)-1-phenanthro[9,10-]imidazol-2-yl)-,-diphenyl-(2-[1,1'-biphenyl]vinyl)-4-amine (NSPI-TPA), 4'-(1-(2-methylnaphthalen-1-yl)-1-phenanthro[9,10-]imidazol-2-yl)-,-diphenyl-(2-[1,1'-biphenyl]vinyl)-4-amine (MNSPI-TPA), 4-(2-(4'-(diphenylamino)-(2-[1,1'-biphenyl]vinyl)-4-yl)-1-phenanthro[9,10-]imidazol-1-yl)-1-naphthalene-1-carbonitrile (SPNCN-TPA) and 4-(2-(4-(9-carbazol-9-yl)styryl)-1-phenanthro[9,10-]imidazol-1-yl)naphthalene-1-carbonitrile (SPNCN-Cz) were analyzed. The conjugation length in the emitters is not conducive to pure emission and hence, a molecular twisting strategy was adopted in NSPI-TPA, MNSPI-TPA, SPNCN-TPA and SPNCN-Cz to enhance pure emission. The emissive state (HLCT) of twisted D-π-A molecules containing both LE and CT (HLCT) states was tuned for high PL ( ) (LE) and high exciton utilization ( ) (CT) efficiencies by replacing triphenylamine (strong donor) with carbazole (weak donor).

Efficient donor-acceptor host materials for green organic light-emitting devices: non-doped blue-emissive materials with dual charge transport properties.

A hybrid inorganic-organic light-emitting diode using Ti-doped ZrO as an electron-injection layer.

We have fabricated stable efficient iridium(iii)-bis-5-(1-(naphthalene-1-yl)-1-phenanthro[9,10-]imidazole-2-yl) benzene-1,2,3-triol (acetylacetonate) [Ir(NPIBT) (acac)] doped inverted bottom-emissive green organic light-emitting diodes using Ti-doped ZrO nanomaterials as the electron injection layer. The current density () and luminance () of the fabricated devices with Ti-doped ZrO deposited between an indium tin oxide cathode and an Ir(NPIBT) (acac) emissive layer increased significantly at a low driving voltage (V) compared with control devices without Ti-doped ZrO. The Ti-doped ZrO layer can facilitate the electron injection effectively and enhances the current efficiency ( ) of 2.

Hibiscus sabdariffa affects ammonium chloride-induced hyperammonemic rats.

Hibiscus sabdariffa (HS) is an edible medicinal plant, indigenous to India, China and Thailand and is used in Ayurveda and traditional medicine. Alcoholic extract of HS leaves (HSEt) was studied for its anti-hyperammonemic and antioxidant effects in brain tissues of ammonium chloride-induced hyperammonemic rats. Oral administration of HSEt (250 mg kg(-1) body weight) significantly normalizes the levels of ammonia, urea, uric acid, creatinine and non-protein nitrogen in the blood.
