Abstract

Certain iridium compounds which may comprise an iridium(III)-ligand complex having the general formula: (C^N)2—Ir—(N^N). (C^N) and (N^N) may each represent a ligand coordinated to an iridium atom. The iridium compounds may have a primary phosphorescent photoluminescence peak wavelength in the near-infrared (IR) range. Also, organic devices that use certain iridium compounds. The organic device may comprise an organic layer and the organic layer may comprise any of the iridium compounds disclosed herein. Also, organic devices that use certain metalloporphyrin compounds. The metalloporphyrin compounds may comprise a core porphyrin structure with four pyrrole rings. The metalloporphyrin compounds may have a primary phosphorescent photoluminescence peak wavelength in the near-IR range.
