Abstract

Three-ligand synergistically enhanced aggregation-induced luminescent organometallic platinum complex luminescent material, the general structural formula is: where, is an organic nitrogen heterocycle, including pyridine, pyrimidine, thiazole, benzothiazole, quinoline, isoquinoline, pyrazole , imidazole; R 1 Is the substituent on the represented nitrogen heterocycle; R 2 is a substituent on the benzene ring; R 3 is the substituent on the represented nitrogen heterocycle; ○ is an organic monodentate ligand that can directly form a bond with the platinum metal center; under the synergistic effect of the three ligands, the organometallic platinum complex phosphorescent material obtains aggregation-induced The characteristic of luminescence significantly improves the luminous efficiency of luminescent materials under the conditions of aggregation or high concentration, which is very beneficial to the preparation of high-performance organic light-emitting diodes.

Description

technical field [0001] The invention relates to the technical field of new organic optoelectronic materials, in particular to a triligand synergistically enhanced aggregation-induced luminescent organic metal platinum complex luminescent material. Background technique [0002] Organic light-emitting diode is a device that uses organic light-emitting materials to convert electrical energy into light energy. It has very important application value in the fields of new generation high-end display and solid-state lighting. The light-emitting performance of an organic light-emitting diode is very dependent on the type of organic light-emitting material. The internal quantum efficiency of organic light-emitting diodes prepared from traditional fluorescent materials is only about 25%, and the internal quantum efficiency of organic light-emitting diodes prepared from organometallic platinum complex phosphorescent materials can reach 100%. Therefore, research and development of organ...
