| 摘要 |
Provided in the present invention is a delayed fluorescence compound having molecular formula of a structure that a first electron donor moiety of indolo-[3,2,1-j,k]carbazole and a second electron donor moiety selected from indolo-[3,2,1-j,k]carbazole, carbazole, or triphenylamine are bonded to an electron acceptor moiety selected from dibenzothiophene sulfone or diphenyl sulfone, wherein the electron acceptor moiety is bonded to position 3 of the indolo-[3,2,1-j,k]carbazole. The delayed fluorescence compound in the present invention solves a problem of low quantum efficiency of a fluorescence substance. |
