Here, we report the new deep green BODIPY fluorescence emitters and efficient deep green hyperfluorescence (HF) devices. The KHU-FD1 exhibits the pure and bright deep green emission peak at 531 nm with 22 nm of narrow spectral width. With 30 wt% of 4CzIPN and 0.5 wt% of KHU-FD1, HF device exhibited the 20.5% of the maximum efficiency, and 531 nm of emission peak with...
