| 摘要 |
Provided in the present invention is a delayed fluorescence compound having molecular formula that each of a first electron-donating moiety of indolo-[3,2,1-j,k]carbazole and a second electron-donating moiety selected from indolo-[3,2,1-j,k]carbazole, carbazole, and triphenylamine is bonded to an electron-accepting moiety selected from pyridine, phenyl pyrimidine, phenyl triazine, and dibenzothiophene sulfone by a linker which is benzene. The delayed fluorescence compound in the present invention solves a problem of low quantum efficiency of a fluorescence substance. |
