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 may include a molecule of Formula I wherein an alkyl substituent at position R′5 results in high efficiency and operational stability in the organic light emitting device. Additionally or alternatively, the emissive layer may include a metal-ligand complex in which the ligand is an aryl or alkyl substituted phenylpyridine ligand.
Abstract:
Devices containing a particular combination of organic compounds are provided. In particular, the devices contain twisted aryl compounds having extended conjugation (i.e., the twisted aryl is substituted with an additional aryl group) in combination with dibenzothiophene or dibenzofuran containing host materials. The organic light emitting devices may provide improved stability color, lifetime and manufacturing. Compounds containing a twisted aryl having extended conjugation are also provided.
Abstract:
Novel organic compounds comprising ligands containing a boron-nitrogen heterocycle are provided. In particular, the compound is a metal complex comprising a ligand containing an azaborine. The compounds may be used in organic light emitting devices to provide devices having improved photophysical and electronic properties.
Abstract:
Heteroleptic compounds containing phenylpyridine and phenylbenzimidazole are provided. The compounds may be used in organic light emitting devices, particularly as emissive dopants in the emissive layer of such devices.
Abstract:
Compounds comprising a triphenylene moiety and a benzo- or dibenzo-moiety are provided. In particular, the benzo- or dibenzo-moiety has a fused substituent. These compounds may be used in organic light emitting devices, particularly in combination with yellow, orange and red emitters, to provide devices with improved properties.
Abstract:
This invention involves a compound and hollow insulator and its manufacturing method thereof. The insulator includes a connector, an insulating tube and petticoat. The insulating tube is made by winding epoxy glass fiber. The petticoat is arranged outside the insulating tube. The connector is arranged at the two ends of the insulating tube. The petticoat becomes an integrated body through injecting silicon sulfide rubber at the high-temperature so that the electrical and mechanical property is better. Meanwhile, the ratio of the qualified products is improved.
