Organometallic Phosphorescent Material with Pyrene or Perylene-Based Cyclometalating Ligands or their Analogs and Electro Luminescent Devides Employing the Phosphorescent Materials

Researchers at Arizona State University have developed organic materials having strong phosphorescent emission in the near infrared region (i.e., from about 650 nm to about 2000 nm, or from about 650 nm to about 1000 nm) using organometallic complexes. These complexes offer high efficiency, wavelength-tunable phosphorescent emitters in the fabrication of near infrared phosphorescent organic light emitting devices (PhOLEDs) and/or as absorbers in organic solar cells.
