Patent ID: 8119255

Claim:
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 2 hybridized carbon atom on ring B; 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 1 and R 2 , respectively, wherein each of R 1 and R 2 represents one or more independently selected substitutions located on any position of their respective rings, wherein each of the substitutions are fused or linked to their respective rings, and wherein each of the substitutions are independently selected from the group consisting of: alkyl, heteroalkyl, aryl, and heteroaryl; 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).
