| titleOfInvention | Based on dibenzofuran group n-type thermally excited delayed fluorescence aromatic phosphine oxide host material, synthesis method and application |
| abstract | The invention discloses an aromatic phosphine oxide host material, a synthesis method and an application thereof based on an n-type thermally excited delayed fluorescence of a dibenzofuran group, and relates to a class of phosphine oxide host materials, a synthesis method and an application thereof. The invention aims to solve the technical problem that the thermal excitation delayed fluorescent material is prone to photo-oxidation and electro-oxidation process during device operation, resulting in poor stability of the excited state of the thermal excited delayed fluorescent molecule. The material is formed by introducing 2 to 4 diphenylphosphine groups at the 2, 4, 6, and 8 positions of dibenzofuran. The method: mix the raw materials, pour into ice water, extract, obtain an organic layer and oxidize , extraction, drying, purification, that is. The host material of the present invention stabilizes the excited state of thermally excited delayed fluorescent molecules through the electron-withdrawing induction ability of the dibenzofuran aromatic phosphine oxide host material, thereby obtaining efficient and stable thermally excited delayed fluorescent emission. The material of the invention is used as the main body of the light-emitting layer or the exciton blocking layer to prepare electroluminescent devices. |
