The optimal device: ITO/DPAInT2/DPAInF/TCTA/DFBTA/Alq3/LiF/Al displayed impressive device characteristics, including a maximum external quantum efficiency (η ext) of 3.7% (12.9 cd A -1) and a maximum brightness at 168 000 cd m -2. © The Royal Society of Chemistry 2009.[SDGs]SDG7Benzothiadiazole; Device characteristics; External quantum efficiencies; Non-doped; Optimal devices; Organic light-emitting diodes; Photoluminescence quantum yields; Hole mobility; Light; Light emission; Light emitting diodes; Luminescence; Organic light emitting diodes (OLED); Photovoltaic effects; Quantum efficiencyjournal article10.1039/b814082k2-s2.0-58849085428
