| titleOfInvention | High quantum yield phosphorescent emissive material, preparation method and application thereof |
| abstract | The invention relates to the technical field of organic optoelectronic materials, in particular to a phosphorescent emitting material with high quantum yield and a preparation method and application thereof. A phosphorescent emitting material with high quantum yield includes a host compound and a guest compound; the structural formula of the guest compound is as follows: R is selected from at least one of H, F, Cl, Br and I. The phosphorescent emitting material of the present invention exhibits organic room temperature pure phosphorescence emission, and the quantum yield is as high as 64%, and the ISC efficiency of the excitons can be adjusted by changing the excitation wavelength, so that the emitting material selectively emits green phosphorescence or cyan fluorescence. |
