Description

technical field

[0001] The invention belongs to the field of organic electroluminescence and can be applied to the fields of color flat panel display and illumination. It specifically relates to a Pt-M complex phosphorescent material supported by a rigid triphosphine ligand and its application in an organic light-emitting diode. A high-efficiency organic light-emitting diode based on a phosphorescent Pt-M complex is prepared by a solution method. Background technique

[0002] An organic light emitting diode (OLED) is a device with a sandwich structure consisting of an anode, a luminescent film and a cathode, which can convert electricity into light under the action of a low DC voltage of 3-12V, that is, organic electroluminescence. Compared with the first-generation display technology represented by cathode ray tube (CRT) and the second-generation display technology represented by plasma (PDP) and liquid crystal (LCD), OLED, as the core of the third-generation display techno...
