| titleOfInvention | A kind of compound using imidazocarbazole as acceptor and application thereof |
| abstract | The invention discloses a compound using imidazocarbazole as an acceptor, and belongs to the technical field of organic electroluminescent materials. The general structural formula of this type of compound is shown in formula (I), wherein, Ar 1 is an electron donating group or an electron accepting group, and when Ar 1 is an electron donating group, it is selected from substituted or unsubstituted carbazole base, acridine group, furanyl group, amino group, 9,9-dimethyl-9H-fluorenyl group, phenazinyl group or phenothiazinyl group; when Ar 1 is an electron accepting group, it is selected from substituted or unsubstituted Substituted triazinyl, pyrimidinyl, pyridyl, phenanthrene, sulfone, benzimidazolyl, triphenylboranyl, phenanthryl, benzophenone or spirobifluorenyl. The new compound modified by introducing a specific group into a specific position in the present invention has good energy transmission ability and charge transmission ability, has suitable HOMO/LUMO value and triplet energy, and can be used in organic electroluminescence devices to achieve high Brightness, low voltage, high efficiency and long life. The general structural formula is shown in formula (I): |
