The present disclosure relates to the field of organic light-emitting materials, and more particularly, to a thermally activated delayed fluorescence material having red, green, or blue color, a synthesis method thereof, and application thereof. The thermally activated delayed fluorescence material having red, green, or blue color has the following structural formula: the present disclosure provides a novel thermally activated delayed fluorescence material having red, green, or blue color which has a lower singlet triplet energy level difference, a high RISC rate constant (kRISC), and a high photoluminescence quantum yield (PLQY). It has significant characteristics of a thermally activated delayed fluorescence material and a long service life that can be used in an electroluminescent display and a light-emitting equipment structure which are mass produced.
