  • Publication number: 20250059223
    Abstract: The present invention is in the field of organic electroluminescence, and specifically relates to a fused ring carbazole tetradentate metal platinum (II) complex and use thereof. In the present invention, a tetradentate metal platinum (II) complex phosphorescent material is obtained by introducing a five-membered heterocyclic system such as benzofuran or benzothiophene at the 5, 6-positions of carbazole. Increasing the ratio of the local state (LE) in the excited triplet state of the cyclic tetradentate platinum (II) complex leads to a lower shoulder peak, which improves the luminescence color purity of the materials, which in turn increases device lifetime. The materials provided by the present invention all have good chemical stability and thermal stability and are easy to fabricate an evaporation-type OLED device.

    Abstract: The present invention provides a high radiation rate platinum complex based on 1,8-substituted carbazole and an application thereof. The luminescent material of the present invention can efficiently control the excited state properties of material molecules by introducing substituents at 1-, 8-position of carbazole, which increases components of metal-to-ligand charge transfer state (MLCT), and improves the intersystem crossing rate of molecules; at the same time, the introduction of substituents at the 1-, 8-position of carbazole can increase the dihedral angle thereof with a pyridine ring, which can improve the rigidity of molecules, effectively reduce the energy consumed by the vibration and rotation of the carbazole ring in the molecules, and reduce non-radiative attenuation. The described factors can jointly increase the radiation rate of material molecules and shorten the lifetime of the excited state.
