While the demonstration of the first OLED emitting thermally activated delayed fluorescence (TADF) in Advanced Materials1-3 in 2009 by our group gave a glimpse of TADF's potential, our successive report in Nature4-6 in 2012 of a TADF-based OLED with an internal quantum efficiency of nearly 100% grabbed the attention of researchers world-wide and established TADF as a truly promising technology. First, we mention about the recent advanced TADF OLEDs aiming for blue and high stability by engineering molecular structures7 and device architectures8. Further, we will introduce our recent efforts on the advanced technologies such as long persistent luminescence (LPL)9, singlet fission10 and organic semiconductor laser diodes (OSLDs) 11.
