“In the field of electroluminescent materials, researchers have employed a metal coordination coordinated end effector steric hindrance strategy to successfully construct a novel helical chiral electroluminescent material racemate and prepare optically pure isomers. The experimental results show that the complex has excellent thermal stability and deep red/near-infrared luminescence properties, and the prepared chiral isomer exhibits strong circularly polarized electroluminescence performance. The related work provides new ideas for the development of efficient deep red/near-infrared luminescent materials and chiral electroluminescent devices.”
