Disclosed are a red, green and blue thermally activated delayed fluorescent material, a synthesis method therefor and use thereof. The red, green and blue thermally activated delayed fluorescent material has a general formula (I). The disclosed red, green and blue thermally activated delayed fluorescent material has a novel structure and a lower single triplet energy level difference. The thermally activated delayed fluorescent material has significant characteristics and long service life, and can be applied to mass-produced electroluminescence-based display and light-emitting device structures. |
