Problems solved by technology

At present, there are the following categories of organic / polymer light-emitting materials, which have the following disadvantages: 1. Small organic molecule electroluminescent materials have crystallization phenomena in the preparation and operation of devices, which reduces the life of electroluminescent devices. At the same time, small organic molecules The preparation method of EL materials mainly depends on vacuum evaporation, the preparation process is complicated, and the production cost is high; 2 Conjugated polymers, the preparation process is complicated, the solubility is not ideal, and the processing is difficult; 3 The polymer doped with metal-organic complexes is easy Phase separation occurs, uneven dispersion occurs, material performance decreases, fluorescence intensity decreases, and fluorescence lifetime decreases; 4. There are many synthesis methods for polymer metal complex luminescent materials, and there are mainly shortcomings such as cross-linking, poor solubility, and poor film-forming properties, which cannot meet the requirements of preparation. Electroluminescent devices with excellent performance
Most of the polymerized 8-hydroxyquinoline metal complexes have poor solubility and film-forming properties. When the 8-hydroxyquinoline metal complexes account for up to 20% of the polymer weight, the polymers are difficult to dissolve in common solvent

Abstract

Invention this person who involves high polymer contain 8-hydroxyl quinoline metal cooperate with polymer of thing give light the material and make France and use, organic / the high polymer and electricity send and give out light materials there is extensive application in the field of photoelectron. At present it is the organic / last shortcoming exist high plymer, it is prepare there aren't performance the good electricities not to make its unable. Last heavy luminescence material invention, 8 among material-cooperate with hydroxyl quinoline metal the contents high polymer 1-30% of weight for thing. This material from one kin alkenes been the single with containin by 8-hydroxyl quinoline mix alkenes of body the single and through free radical tool formate not lasting 8 first-hydroxyl quinoline mix High polymer, lie in it is to reserve vacancy since have 8-metal cooperate with thing of through cooperating not turning into not for 8ing-hydroxyl quinoline metal cooperate with high polymer of thing of at quinoline hydroxyl. Have craft to be simple, equipment with little investment aveantage. Will give out light material can use as organic / high polymer electricity is it give out light level show electricity of device is it give out light material and electron transmit materials to send.
