摘要： Novel heteroleptic iridium carbene complexes are provided. The complexes have lower-than expected sublimation temperatures, which is beneficial for the processing of these materials in solid state applications. Selective substitution of the ligands provides for phosphorescent compounds that are suitable for use in a variety of OLED devices. The carbene complexes can also be used as materials in a hole blocking layer and/or an electron transport layer to improve device performance.

摘要： Compounds comprising the formula L1L2MX wherein L1, L2, and X are distinct bidentate ligands that form an octahedral complex on the metal M, wherein M is a metal with an atomic weight greater than 40. Compounds of this formula are sublimated more facilely than octahedral metal complexes where L1, L2, and X are not distinct bidentate ligands. Organic light emitting devices are also described wherein the emissive layer may comprise a host material containing an emissive molecule of formula L1L2MX, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, and the emissive molecule is selected from the group of phosphorescent organometallic complexes, including iridium complexes of the formula L1L2IrX wherein L1, L2, and X are distinct bidentate ligands.
