Achieving 21% External Quantum Efficiency for Nondoped Solution‐Processed Sky‐Blue Thermally Activated Delayed Fluorescence OLEDs by Means of Multi‐(Donor/Acceptor) Emitter with Through‐Space/‐Bond Charge Transfer
Abstract Although numerous thermally activated delayed fluorescence (TADF) organic light‐emitting diodes (OLEDs) have been demonstrated, efficient blue or even sky‐blue TADF‐based nondoped solution‐processed devices are still very rare. Herein, through‐space charge transfer (TSCT) and through‐bond c...
