Abstract

The invention relates to a series of olefin monomer of a polymerisable functional group 8-hydroxyquinoline metal complex, its preparation process and use thereof, wherein the preparation process consists of synthesizing alkene monomers containing 8-hydroxyquinoline through reaction between vinyl compound containing reacting function group with modified 8-hydroxyquinoline, then compounding with metallic ions and 8-hydroxyquinoline.

Description

technical field [0001] The present invention relates to a class of ethylenic monomer containing 8-hydroxyquinoline metal complex and its preparation method and application. In particular, it is an olefinic monomer capable of being polymerized with other types of olefins to form a linear copolymer, an 8-hydroxyquinoline metal complex containing a polymerizable functional group, and its preparation method and use. technical background [0002] With the advent of the information age, new, high-efficiency, and light-weight organic electroluminescent flat-panel displays (OLEDs) have attracted more and more attention, and have become a research hotspot at home and abroad in recent years. As the whole society pays more attention to health, environmental protection, resources and energy utilization, people put forward higher and higher requirements for luminescent materials. Especially for the production of luminescent materials with special processing properties and special photoe...
