Here, we explored the possibility of using cycloparaphenylenes (CPP) within a donor-acceptor TADF emitter design. contains four electron-donating moieties connected to a . In the 15 wt % doped in CzSi film, showed sky-blue emission with λ = 475 nm, Φ = 29%, and triexponential emission decays with τ of 4.4, 46.3, and 907.8 ns. Solution-processed OLEDs using exhibited sky-blue emission with an λ of 465 nm and an EQE of 1.0%.
在这里，我们探索了在给体-受体 TADF 发射器设计中使用环对苯撑（CPP）的可能性。该化合物包含四个与相连的电子给体部分。在掺杂质量分数为 15%的 CzSi 薄膜中，以 475nm 的 λ发射出天蓝光，Φ为 29%，并呈现出四指数衰减，τ分别为 4.4、46.3 和 907.8ns。使用该化合物制备的溶液处理 OLED 以 465nm 的 λ发射出天蓝光，EQE 为 1.0%。
