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.

通过收获三重态激子的近红外发光材料：分子设计，性质和在有机发光二极管中的应用

由于近红外（NIR）发射材料在有机发光二极管，生物成像，军事等领域具有潜在的应用前景，因此引起了相当大的关注。对近红外（NIR）发射材料和器件的研究受到基本和实际应用需求的推动。在这些发达的发射近红外光的材料中，过渡金属络合物和可激发三重态激子的热活化延迟荧光（TADF）分子具有巨大的潜力，因为它们的理论内部量子效率可达到100％。本文对过渡金属配合物和TADF分子的这些近红外发射材料的发展进行了综述，此外，它为许多学科领域的广泛应用提供了清晰的前景。
