英文摘要： Three classes of the donor(D)-acceptor(A)-based cyclo- metalated ligands and the resulting near-infrared-emitting platinum (II) complexes with one of the frameworks of D-A1-A, D-A-D and D-A-D1-A-D will be designed and synthesized, in which carbazol and triphenylamine derivatives are used as electron- donoring units (D and D1), aryl-fused thiadiazole and aryl isoquinoline derivatives are used as electron-accepting units (A and A1), respectively. By studying the influence of the donor and acceptor structures, as well as the molecular building model, on photoelectronic properties of their resulting platinum (II) complexes, the molecular building rule of the high-efficiency near-infrared- emitting platinum (II) complexes will be revealed. Furthermore, the independent innovated near- infrared-emitting platinum (II) com- plexes and their polymer light-emitting devices (PLEDs) with high performance will be obtained. This project is available to enrich and develop the near-infrared-emitting materials. It has an important theoretical and realistic significance for solving the key issues in the near-infrared-emitting PLEDs, such as low luminescent efficiency and radiance intensity, further promoting the application of cyclometalated platinum (II) complexes in the near-infrared- emitting devices.
