Abstract
Multiresonance thermally activated delayed fluorescence (MR-TADF) emitters are promising candidates for organic light-emitting diodes (OLEDs) with high color quality. However, in most cases, noble metal–containing phosphors are required as sensitizers for MR-TADF emitters to improve their electroluminescence (EL) performances, which may lead to high cost and environmental pollution. Herein, an efficient purely organic room-temperature phosphorescence (RTP) material, 3,2-PIC-TXT, with fast phosphorescence radiation is developed. It not only exhibits impressive EL performances as an emitter with an outstanding external quantum efficiency (EQE) of 33.2%, higher than that of Ir(ppy) 3 (25.2%), but also functions…
