The invention discloses a thermally-induced delayed fluorescence semiconductor, and a preparation method and application thereof. The thermally-induced delayed fluorescence semiconductor uses polycyclic aromatic hydrocarbon containing electron withdrawing groups as a molecular mother nucleus to construct a novel organic electroluminescent material, and material molecules have high triplet state energy level, high PLQY and high glass transition temperature. When the thermally-induced delayed fluorescence material is used as a light-emitting material of a light-emitting layer, due to the high triplet state energy level, effective energy transfer from a host material to a guest material can be promoted, energy return is reduced, and the light-emitting efficiency of an OLED device is improved. The HOMO energy level of the thermally-induced delayed fluorescent material is high, the Fermi energy level matching performance of the thermally-induced delayed fluorescent material with a hole injection layer and a hole transport layer is improved, the hole injection performance of material molecules is further improved, meanwhile, a planar rigid framework of the molecules is beneficial to charge transport, the turn-on voltage of a related electroluminescent device can be very efficiently reduced, and the current efficiency under high current density is maintained.
