Abstract

We developed two symmetrical green MR-TADF emitters, BpICDPA and BpIC-Cz, based on the rigidification and regulation of molecular orbitals (MO) engineering strategies. Both emitters exhibited pure green emission with narrow FWHM below 25 nm and high PLQY over 84%. Among the fabricated OLEDs, BpICCz-device showed maximum external quantum efficiency (EQEmax) of 25.7% with alleviated efficiency roll-off characteristics (EQE1000nits=24.3%) and longer device-lifetime (LT₉₀) of 291 h at the initial luminance of 1000 nits.
