Abstract

Three emitters having a donor-phenyl-acceptor structure are considered as thermally activated delayed fluorescence (TADF) materials. They present different triplet excited-state energies depending on the substitution positions. Consequently, two materials exhibit blue emission with TADF properties. The OLEDs based on o-CzXTN provided a maximum EQE as high as 10.6%.
