Hybridized local and charge transfer dendrimers with near-unity exciton utilization for enabling high-efficiency solution-processed hyperfluorescent OLEDs

Two dendrimers, called D-TTT-H and D-TTT- t Bu, were prepared, which exhibits both hot exciton process and TADF characteristic simultaneously in solid state. The solution processable OLED showed an EQE max of 30.88% employing D-TTT-H as a sensitizer.
