Abstract

To produce efficient deep-blue emitters, a new family of thermally activated delayed fluorescence (TADF) molecules based on dibenzo-fused phosphacycles was designed. OLEDs employing a phenothiaphosphine sulfide derivative as a TADF emitter displayed blue electroluminescence with a maximum external quantum efficiency of 13% and CIE color coordinates of (0.15, 0.23).
