Type: article

Abstract: High Resolution Image Download MS PowerPoint Slide Here, we explored the possibility of using cycloparaphenylenes (CPP) within a donor–acceptor TADF emitter design. 4PXZPh-[10]CPP contains four electron-donating moieties connected to a [10]CPP . In the 15 wt % doped in CzSi film, 4PXZPh-[10]CPP showed sky-blue emission with λ PL = 475 nm, Φ PL = 29%, and triexponential emission decays with τ PL of 4.4, 46.3, and 907.8 ns. Solution-processed OLEDs using 4PXZPh-[10]CPP exhibited sky-blue emission with an λ EL of 465 nm and an EQE max of 1.0%.
