Solution-processed organic light-emitting diodes (s-OLED) consisting of TAPC/TmPyPB interfacial exciplex host and polymer PAPTC TADF emitter are prepared, simultaneously displaying ultralow voltages (2.50/2.91/3.51/4.91 V at luminance of 1/100/1000/1000 cd m), high efficiencies (14.9%, 50.1 lm W), and extremely low roll-off rates (J of 63.16 mA cm, L of ca. 15000 cd m). Such performance is distinctly higher than that of pure-PAPTC s-OLED. Compared to pure-PAPTC, the advanced emissive layer structure of TAPC:PAPTC/TmPyPB is unique in much higher PL quantum yield (79.5 vs 36.3%) and nearly 4-fold enhancement in k of the PAPTC emitter to 1.48 × 10 s.
制备了由 TAPC/TmPyPB 界面激基复合物主体和聚合物 PAPTC TADF 发射器组成的溶液处理有机发光二极管(s-OLED),同时显示出超低电压(亮度为 1/100/1000/1000 cd m 时的 2.50/2.91/3.51/4.91 V)、高效率(14.9%,50.1 lm W)和极低的滚降率(J 为 63.16 mA cm,L 约为 15000 cd m)。这种性能明显高于纯 PAPTC s-OLED。与纯 PAPTC 相比,TAPC:PAPTC/TmPyPB 的先进发射层结构具有更高的 PL 量子产率(79.5% 对 36.3%)和 PAPTC 发射器的 k 值增加近 4 倍,达到 1.48×10 s。
