Certain iridium compounds which may comprise an iridium(III)-ligand
complex having the general formula: (C^N).sub.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.
