Ester-functionalized thermally activated delayed fluorescence materials

Abstract

A family of thermally activated delayed fluorescence (TADF) materials functionalized with carboxylate esters is presented herein. Owing to their suppressed concentration-quenching effect in neat films, these ester-functionalized TADF emitters could be applied to the fabrication of non-doped organic light-emitting diodes, demonstrating high external electroluminescence quantum efficiencies of 6.3–18.7%.
