A kind of red light organic electrophosphorescent material, preparation method and application thereof |
| abstract |
The invention discloses a red light organic electro-phosphorescent material, a preparation method and application thereof, and belongs to the field of organic optoelectronic materials. Among them, the red light organic electrophosphorescent material of the present invention solves the problem that the existing phthalazine tricyclic metal iridium complex is sensitive to the doping concentration and is prone to concentration quenching; the preparation steps are: derivatizing chlorophthalazine Add substituted phenylboronic acid or substituted phenylboronic acid ester, and react for a period of time in the presence of base, catalyst and solvent to obtain phthalazine ligands; or add base and solvent to substituted diphenylamine or substituted carbazole, and then add The chlorophthalazine derivative is reacted for a period of time to obtain phthalazine ligands; the obtained phthalazine ligands are mixed and reacted with iridium raw materials and a solvent for a period of time to obtain a red light organic electrophosphorescent material. |
