Zusammenfassung:The disclosure relates to the technical field of preparation of circularly polarized luminescence materials, in particular to a central chirality induced helical chiral tetradentate cyclometalated platinum (II) complex, an electronic device and application thereof. The central chirality induced helical chiral tetradentate cyclometalated platinum (II) complex provided in the disclosure has a general structure as shown in formula (1) or (I') in which (I) and (I') are enantiomers to each other:Helical chiral metal complex molecules can autonomously induce 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 helical 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 elements.
