| abstract |
The invention relates to the technical field of organic light-emitting materials, in particular to a red, green and blue thermally activated delayed fluorescent material, a synthesis method and application thereof; the red, green and blue thermally activated delayed fluorescent material has the following general formula: The red, green and blue thermally activated delayed fluorescent material provided by the invention has novel structure, low single triplet energy level difference, fast inverse intersystem crossing constant (kRISC) and high photoluminescence quantum yield (PLQY). The thermally activated delayed fluorescent material has remarkable properties and long service life, and can be used in mass-produced electroluminescence-based displays and light-emitting device structures. |
