Abstract

In this study, we designed two new deep blue MR-type emitters TPD4PA and tBu-TPD4PA. Both emitters showed deep blue photo luminescent emissions of ~450nm and achieved very small EST and high rate of reverse intersystem crossing of ~2.5 × 10⁵ s^-1. The TADF devices showed maximum external quantum efficiencies of 30.7 and 32.5% respectively.
