Abstract

The invention discloses a monomer for an organic electro-phosphorescent polymer. The monomer for the organic electro-phosphorescent polymer is formed by using end alkene terminal olefin beta-diketone as a ligand and complexing metal iridium ions. The structure of the monomer is as follow, wherein R is a hydrogen atom or a fluorine atom. It is proved that the monomer for the organic electro-phosphorescent polymer is an electroluminescent material containing a polymerization activity center and can be used as an organic electroluminescent material or is used for preparing the organic electro-phosphorescent polymer.

Description

technical field [0001] The invention relates to a monomer for an organic electrophosphorescent polymer, which is an iridium-containing complex with terminal alkenyl β-diketone. Background technique [0002] With the development of the information age, more and more attention has been paid to organic electroluminescent flat panel displays (OLEDs) with high efficiency, energy saving and light weight. Luminescent devices put forward higher requirements for luminescent materials. Organic electroluminescent devices can be divided into small molecule organic electroluminescent devices and polymer organic electroluminescent devices according to their materials. [0003] When small molecule organic electroluminescent devices are used in practice, thin-layer crystallization is prone to occur, which affects the life of the device. [0004] In order to solve the problems existing in small molecule organic electroluminescent devices, the best way is to design and synthesize light-emit...
