Solution‐processable thermally activated delayed fluorescence (TADF) emitters have received tremendous attentions in recent years due to their intrinsic merits of theoretical 100% exciton harvesting capability and excellent compatibility to low‐cost and easily scalable solution processes. Herein, a comprehensive review of solution‐processable TADF emitters is presented, including small molecules, dendrimers, and polymers. Their molecular design, optoelectronic properties, and device performances are summarized, and specific emphasis is placed on the structure–property relationships of these emitters. This review not only offers a guideline for designing highly efficient TADF emitters compatible with solution‐processed organic light‐emitting diodes, but also paves further directions for the development of solution‐processable TADF emitters.
