These devices may be used to provide improved lifetime for blue emitting devices.
摘要:
Organic devices comprising an organic layer, wherein the organic layer is non-electroluminescent and comprises a cross-linked metal complex. The cross-linked metal complex may be formed by cross-linking a cross-linkable iridium complex, which comprises a set of ligands coordinated to a central iridium atom. One or more of the ligands have attached thereon, one or more polymerizable groups that are able to polymerize with other molecules to form intermolecular covalent bonds. In some cases, the organic layer may also comprise a dopant. Also provided are a method of making an organic light-emitting device, an iridium complex, and an organic-light emitting device using certain iridium complexes.
