“In the field of electroluminescent materials, researchers have successfully constructed a racemic helical chiral electroluminescent material with deep red/near-infrared luminescence properties using a metal coordination coordinated end effector steric hindrance strategy, and prepared optically pure isomers. This material exhibits strong circularly polarized electroluminescent properties, providing new ideas for the development of efficient deep red/near-infrared luminescent materials and chiral electroluminescent devices.”
