The invention relates to a 9,10-dihydro-acridine derivative having a structure of Formula (I). The HOMO and LUMO levels of the 9,10-dihydro-acridine derivative are distributed on different electron donating and electron withdrawing groups, such that the HOMO and LUMO levels are separated, achieving a small ΔEST. The 9,10-dihydro-acridine derivative can be used as a TADF material in an organic light-emitting device. The dihydro-acridinyl group in the electron donating group is linked to a dibenzoheterocyclic ring. Introducing modifying groups allows adjustment of triplet and singlet energy levels of the compound, enabling the TADF material to have a high luminescence efficiency in blue and deep blue regions. The invention also relates to an organic light-emitting device having at least one functional layer containing the 9,10-dihydro-acridine derivative. When the compound is used as a guest luminescent material in a light emitting layer, an OLED device of high blue light emitting efficiency is obtained.
