Thermally activated delayed fluorescence (TADF) materials are the emerging emitters for organic light-emitting devices (OLEDs) which could realize 100% exciton utilization in optimal conditions. To meet the requirements of low-cost and mass-production for practical application, we developed a series of highly efficient TADF small molecules, dendrimers, and polymers, which were soluton-processable. Throughout this investigation, the fundamentals of the emerging TADF emitters were explored, which are promising for the applications of displays, lighting, visible light communication, and medical treatments. The state-of-the-art performances were demonstrated via molecular design and device engineering to maximize the exciton utilization under the electroluminescence processes
