Abstract: Disclosed are a central chirality induced spiro chiral tetradentate cyclometalated platinum (II) and palladium (II) complex-based circularly polarized luminescence material and an application thereof. Spiro chiral metal complex molecules can be autonomously induced by a whole tetradentate ligand to coordinate with metal ions in a less sterically hindered manner by means of a central chiral fragment La in the tetradentate ligand, to form an optically pure spiro chiral metal complex-based circularly polarized luminescence material, without need for chiral resolution. Moreover, the material has high chemical stability and thermal stability, and has important applications in circularly polarized luminescence devices.
