  • Patent number: 11613530
    Abstract: A thermally activated delayed fluorescent molecular material, a method for synthesizing the same, and an organic electroluminescent device are provided. The thermally activated delayed fluorescent molecular material includes an electron donor and an electron acceptor containing an indenyl group. A phenyl group in diphenylamine or triphenylamine in a donor molecule is replaced with an indenyl group, so that the electron-donating ability of the donor is increased, and the non-radiative transition rate is effectively suppressed, thereby increasing the photoluminescence quantum yield (PLQY) of the molecule. Further, the torsion angle between the electron donor and the electron acceptor is also increased, while the electron cloud overlap between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) is reduced, thereby obtaining a smaller ?EST value.

  • Patent number: 11552254
    Abstract: A thermally activated delayed fluorescent molecular material, a synthesizing method therefor, and an electroluminescent device are provided. The thermally activated delayed fluorescent molecular containing an indenobenzoselenoheteroaromatic ring donor is synthesized, so that an electron donating ability of the donor is increased, and an non-radiative transition rate is effectively inhibited, thereby increasing photo-luminescence quantum yield (PLQY) of the molecule; and increasing the twist angle between the electron donor and the electron acceptor. Meanwhile, electron cloud overlapping between highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) is reduced, thereby obtaining a smaller ?EST value. The organic electroluminescent device adopts the thermally activated delayed fluorescent molecular material prepared according to the synthesizing method, and thus has high luminous efficiency and long service life.
