文摘
Efficient and tunable thermally activated delayed fluorescence emitters are presented by C.-C. Wu, K.-T. Wong, and co-workers on page 7560. A toolbox composed of acridine donor units and cyano-substituted acceptor units allows for systematically probing acceptor strengths as well as tunable acceptor confirmations like twist angles. Highly efficient blue-green to yellow OLEDs with up to 31.3% external quantum efficiency are achieved.
