Abstract
Near-infrared (NIR) emitting materials have attracted considerable attention because of their potential applications in organic light emitting diodes, bioimaging, military, etc. The research on NIR-emitting materials and devices is motivated by fundamental and practical application demands. In these developed NIR-emitting materials, transition metal complexes, and thermally activated delayed fluorescence (TADF) molecules, which can harvest triplet excitons, have exhibited significant potential because their theoretical internal quantum efficiency can reach 100%. Herein, the development of these NIR-emitting materials of transition metal complexes and TADF molecules is reviewed and, furthermore, a clear outlook for a broad range of applications in many disciplinary areas is provided.
