Abstract

The invention relates to an ionic type phosphorescent Ag6Cu complex and its preparation method and use. The ionic type phosphorescent Ag6Cu complex has a structural formula of [Ag6Cu{HC(PPh2)3}2(C[triple-bond]CR)3{Ph2P(=X)X}3]<+>A<n->1 / n, wherein X represents the same or different groups of O, S and Se, R represents the same or different groups of aryl, heterocyclic aryl and -aryl-heterocyclic aryl, the heterocyclic aryl and aryl can be replaced through one or more substituents, the substituents are respectively selected from alkyl, alkenyl, alkynyl, alkyloxy, amino, halogen, halogenated alkyl and aryl, and A<n-> represents ClO<4->, PF<6->, SbF<6->, BF<4-> or SiF6<2-> and n is 1 or 2. The invention also relates to an organic light-emitting diode and its preparation method and use. The phosphorescent metal complex is a doped luminescent layer. The prepared organic light-emitting diode produces high performance organic electroluminescence and can be used for panel display.

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. Specifically related to a class of Ag 6 Cu heteroheptanuclear metal-organic alkyne complexes for the preparation of organic light-emitting diodes. Background technique

[0002] Organic electroluminescence is a light-emitting phenomenon in which an organic light-emitting diode (OLED) directly converts electrical energy into light energy under the action of a low DC voltage of 3-12V. It has very broad applications in the fields of flat panel display and lighting. Compared with traditional lighting and display technologies, organic electroluminescence has many advantages such as full-color display, wide viewing angle, high definition, fast response, low power consumption, and low temperature resistance; and organic light-emitting devices have simple structure, ultra-light, ultra-thin , flexible and foldable and...
