Abstract

A strategy for designing highly efficient thermally activated delayed fluorescence (TADF) emitters was reported. TADF emitters with donoracceptordonor (D-A-D)-type structures showed highly efficient TADF because of their small singlettriplet energy gap and large oscillator strength. An organic lightemitting diode containing a D-A-D-type TADF emitter, cis-BOX2, exhibited a high external electroluminescence quantum efficiency of 17.6%.
