Abstract
In this study, we report a fluorescent green emitter based on 4,4‐dfluoro‐4‐bora‐3a,4a‐diaza‐s‐indacene (BODIPY) backbone and its hyperfluroescence (HF) device. Our HF device shows high EQE of 20.0%, emission peak at 532 nm with narrow FWHM of 29 nm and Commission Internationale de l'Eclairage (CIE) of (0.27, 0.68). Moreover, with consideration of good host materials the device realized a long lifetime (LT90) of 210 h at an initial luminance of3,000 cd/m2.
