Abstract:
1. An organic light-emitting device, comprising: a first electrode; a second electrode; a first organic layer disposed between the first electrode and the second electrode, wherein the first organic layer is non-electroluminescent, and wherein the first organic layer comprises a cross-linked metal complex; and a second organic layer disposed between the first electrode and the second electrode, wherein the second organic layer is emissive, and wherein the second organic layer comprises an electroluminescent organic material; wherein the cross-linked metal complex is formed by cross-linking a cross-linkable iridium complex having the formula: wherein L is a ligand coordinated to the iridium; wherein A and B are each a 5 or 6-membered aromatic ring, and wherein A-B represents a bonded pair of aromatic rings coordinated to the iridium via a nitrogen atom on ring A and an sp wherein variable “n” has an integer value of 1-3; wherein X is a carbon or nitrogen atom; wherein P is a polymerizable group with variable “a” having an integer value of 1-5; wherein S is a spacer group that includes one or more linkage units that are each independently selected from the group consisting of: alkylene, heteroalkylene, arylene, heteroarylene, borane, ether, ester, amine, imine, amide, imide, thioether, and phosphine; and wherein each of rings A and B are optionally substituted with groups R wherein: (a) the first electrode is an anode and the first organic layer is in direct contact with the first electrode; or (b) the device further comprises a third organic layer disposed between the first organic layer and the second organic layer; or (c) wherein the structure A-B is or any combination of (a), (b), and (c).
