The tetraphenyibenzene (4Ph)-containing emitters have been demonstrated having a higher light outcoupling efficiency for dopant devices and a superior IQEfor the non-dopant devices. ? 2019 SID.Efficiency; Fluorescence; Molecular orientation; Organic light emitting diodes (OLED); Blue colors; Internal quantum efficiency; Light outcoupling; Non-dopant OLED; Thermally activated delayed fluorescences; Quantum efficiencyA chemical structure approach enhancing light outcoupling of dopant OLEDs and internal quantum efficiency of non-dopant OLEDs having bluish TADF emittersconference paper10.1002/sdtp.129582-s2.0-85081168491
