Abstract
, respectively, verified by the transient absorption spectroscopic study. The resulting solution-processed OLEDs based on the optimal complex afford record external quantum efficiencies of 16.2% at maximum and 13.4% at 1000 nits, representing the state-of-the-art performance for Ag(i) emitters. This work presents an effective approach for the development of short-lived TADF materials for high-efficiency OLEDs.
