High-performance near-infrared organic light-emitting materials and devices

Abstract

As the extension of visible light, near-infrared (NIR) emitting materials have aroused growing interests due to their great potential for applications spanning from military night-vision displays and informationsecured devices to civilian medical diagnostics and phototherapy [1]. However, the development of highly efficient, stable, and low-cost organic NIRemitting materials is still a formidable challenge according to the energy-gap law. We have developed two classes of novel organic NIR-emitting materials including Ir(lll) complexes with extensively π-conjugated ligands and purely organic NIR dyes with high quantum yields.
