Abstract

Highly efficient and stable blue-green thermally-activated delayed fluorescence (TADF) molecules with trifluoromethyl (CF3) groups were developed. Partial modification with CF3 groups at the appropriate position of the donor moiety improved the luminescence efficiency and excited state stability. OLEDs using modified emitters showed improved EQE and operational lifetime compared with unmodified examples.
