Delayed Fluorescence Emitters: Efficient and Tunable Thermally Activated Delayed Fluorescence Emitters Having Orientation‐Adjustable CN‐Substituted Pyridine and Pyrimidine Acceptor Units (Adv. Funct. Mater. 42/2016). (November 2016) - Pan, Kuan‐Chung
Abstract : 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.
