Organic luminescent radicals enable bright circularly polarized light in the near-infrared region
Kyushu UniversityPeer-Reviewed Publication
Circularly polarized luminescent materials emitting red to near-infrared light are of interest for technologies such as 3D displays and bioimaging. However, achieving high emission efficiency, stability, and durability simultaneously has remained a challenge. In a recent study, researchers at Kyushu University developed a new series of small luminescent radicals with exceptional photoluminescence efficiency and photostability. Their work demonstrates how a favorable electronic structure, chirality, and light emission can be achieved in a single molecular system.
