The invention discloses an asymmetric heat-activated delayed fluorescent material, a synthesis method and application thereof. The material has a structural formula shown as formula (1) in the specification, wherein Ar1 and Ar2 are aromatic amine substituent groups of different structures. The invention simultaneously discloses a synthesis method of the asymmetric heat-activated delayed fluorescent material, and also discloses a non-doped OLED device, wherein a luminescent layer is prepared from the asymmetric heat-activated delayed fluorescent material. The asymmetric heat-activated delayed fluorescent material disclosed by the invention has circularly polarized luminescence and aggregation-induced luminescence properties, good thermal stability and excellent luminescent properties, and the synthesis method and purification process are simple. The non-doped OLED device prepared from the heat-activated delayed fluorescent material as the luminescent layer has high luminance and good stability, so that both the luminous efficiency and service life of the OLED device can meet the practical requirements.
