The invention discloses a pyrimidinyl or pyrazinyl or triazinyl group containing anthracenoindenofluorene derivative and a preparation method and application thereof. The pyrimidinyl or pyrazinyl or triazinyl group containing anthracenoindenofluorene derivative is obtained through a Suzuki polymerization reaction. The pyrimidinyl or pyrazinyl or triazinyl group containing anthracenoindenofluorene derivative has relatively good solubility, and after the pyrimidinyl or pyrazinyl or triazinyl group containing anthracenoindenofluorene derivative is dissolved by a common organic solvent, a light emitting layer of an organic light emitting diode is prepared by spin coating, inkjet printing or printing and filming. An electroluminescent device using the pyrimidinyl or pyrazinyl or triazinyl group containing anthracenoindenofluorene derivative as the light emitting layer has relatively good device efficiency, and during preparation of the device, annealing treatment is not required, so that the preparation process is simpler.
