The invention provides an electroluminescent material, a preparation method of the electroluminescent material, and a light-emitting device. The electroluminescent material is of an asymmetric structure, and a tetraphenyl ethylene structure with aggregation induced luminescence is connected with a perylene structure capable of achieving high efficiency by generating triplet state-triplet state fusion, so that the aggregation-induced quenching effect of the perylene structure is effectively inhibited, and film-state luminescence efficiency is improved. Meanwhile, a structure unit with high electron mobility is introduced to improve the carrier transmission balance and increase the composite probability, so that the electroluminescent material which can emit blue light and has high electroluminescent efficiency is achieved, and the preparation method of the electroluminescent material, and the light-emitting device are achieved.
