Patent ID: 7989090

Claim:
An organic light-emitting device comprising: an anode; a cathode; and an organic layer between the anode and the cathode, the organic layer comprising a host material and a metalloporphyrin compound, wherein the metalloporphyrin compound comprises a plurality of pyrrole rings and has a formula: wherein M is a metal; wherein each of R 1 to R 4 is independently selected from the group consisting of an aliphatic moiety, aryl moiety, heteroaryl moiety, and macrocycle moiety; wherein each of R 1 ′ to R 4 ′ is independently selected from the group consisting of a hydrogen, phenyl, mesityl, and methyl; wherein the metalloporphyrin compound has a primary phosphorescent photoluminescence emission peak wavelength in the near-infrared range; and wherein the absorption spectrum of the metalloporphyrin compound overlaps with the emission spectrum of the host material.
