An ionic phosphorescent ptm2 complex and its preparation method and use

Abstract

The invention relates to an ionic phosphorescent PtM2 complex, a preparation method and a purpose thereof. A structure of the complex is shown in a [PtM2{PhP(CH2PPh2)2}2(C=CR1)(C=CR2)]<2+>A<n->2 / n. M is optionally selected as Cu(I), Ag(I) and Au(I); R1 and R2 can be same or different, and can be independently selected from heteroaryl, -aryl-heteroaryl, the heteroaryl and aryl can be substituted by one or more substituent, the substituent is independently selected from alkyl, alkenyl, alkynyl, alkyloxy, amino, halogen, alkylhalide group and aryl; A<n-> can be ClO4<->, PF6<->, SbF6<->, BF4<->, SiF6<2->, and n can be 1, 2. The invention also relates to an organic light-emitting diode, a preparation method and a purpose thereof, by taking the phosphorescent metal complex as a luminescent layer dopant, the prepared organic light-emitting diode has 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 PtM 2 (M=Cu(I), Ag(I), Au(I)) heterotrinuclear 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 , flexi...
