Abstract:
An organic light emitting device is provided. The device has an anode, a cathode and an emissive layer disposed between the anode and the cathode. The emissive layer includes a host material and a dopant, and the host material is selected from the group consisting of: wherein each R represent no substitution, mono-, di-, or tri-substitution, and the substituents are the same or different, and may be alkyl, alkenyl, alkynyl, aryl, thioalkoxy, halo, haloalkyl, cyano, carbonyl, carboxyl, heteroaryl, and substituted aryl, and at least one R for each Compounds I, II, III, or IV includes a carbazole group.
Abstract:
The present invention relates to organic light emitting devices (OLEDs), and more specifically to efficient OLEDs comprising an array of pixels and having reduced pixel shrinkage. The devices of the present invention comprise further relates to materials for use as emissive materials which give reduced shrinkage when incorporated into an OLED.
Abstract:
An organic light emitting device is provided. The device has an anode, a cathode and an organic layer disposed between the anode and the cathode. The organic layer comprises a compound further comprising one or more arylimidazole, aryltriazole, or aryltetrazole derivative ligands coordinated to a metal center. The ligand has the structure:
Abstract:
The current invent relates to the construction and application of a three-line breeding system in the Peruvian scallop×bay scallop southern subspecies hybrids. The said three-line consists of a male sterile line, a maintainer line and a restorer line. A combination of male sterile line and maintainer line is obtained by continuously backcrossing the male sterile individuals selected from F1 inter-specific hybrid families with sperm of the selfing family of the sperm-providing bay scallops until the progenies are all male sterile. The restorer line is obtained by continuously backcrossing selected individuals from the male sterile line with sperm of the selfing family of a bay scallop until the progenies are all hermaphroditic and exhibit excellent production traits. Commercial male sterile brood stocks are produced by backcrossing the male sterile line with the maintainer line and commercial hybrid spats are produced by backcrossing the male sterile line and the restorer line.
Abstract:
Novel phosphorescent tetradentate platinum compounds of Formula I are provided. The complexes contain a dibenzo moiety, which allows for the creation of OLED devices with improved properties when compounds of Formula I are incorporated into such devices. Compounds of Formula I′ that comprise two ligands that contain a 5-membered carbocyclic or heterocyclic ring, one of which contains an imidazole ring with a twisted aryl group attached to N−1 and a second aromatic ring that is attached to the platinum via a carbon atom. These compounds may be advantageously used in OLEDs.
Abstract:
Novel heteroleptic iridium carbene complexes are provided, which contain at least two different carbene ligands. Selective substitution of the carbene ligands provides for phosphorescent compounds hat are suitable for use in a variety of OLED devices.
