Organometallic compounds comprising an imidazole carbene ligand having a N-containing ring fused to the imidazole ring are provided. In particular, the N-containing ring fused to the imidazole ring may contain one nitrogen atom or more than one nitrogen atom. These compounds may demonstrate high photoluminescent (PL) efficiency, Gaussian emission spectra, and/or short excited state lifetimes. These materials may be especially useful as blue phosphorescent emitters.

Embodiments of systems, computer program product, and related computer implemented methods to issue a closed-loop retail prepaid card including a user-designed external face using a chit, the chit being defined by an identification mechanism representing a financial commitment to issue a closed-loop retail prepaid card in an amount associated with a value paid for the chit, are provided. Embodiments of the present invention advantageously provide a service that enables a consumer to purchase, at the storefront of a retail establishment, a chit card that the consumer can subsequently redeem through a graphical user interface of an Internet website for a closed-loop retail prepaid card with a user-designed external face. The user-designed closed-loop retail prepaid card, for example, can be subsequently printed and delivered to an intended recipient. Advantageously, such a service can be made available to any retail establishment that uses a point-of-sale system.

Novel organic compounds containing a twisted aryl group are provided. In particular, the compounds provided contain a 2-phenylpyridine ligand having a twisted aryl group on the pyridine portion of the ligand. The compounds may be used in organic light emitting devices, particularly as emitting dopants. Devices comprising the compounds containing twisted aryl may demonstrate improved color, efficiency, stability and manufacturing. Additionally, methods are provided for making homoleptic Ir (III) compounds which may contain a twisted aryl.
摘要:
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 an emissive material having a transition metal and two or three bidentate ligands, which may be photoactive ligands. The bidentate photoactive ligands may be bound to the transition metal through a carbon-metal bond and a nitrogen-metal bond to form a cyclometallated ring. The organic layer may have the formula LXa-(L)bM, wherein X is a linking group that links two or more ligand L and M is a metal.
