제목 New Green Polymer Emitter Containing Non-conjugated Cyclohexane Units for high performing Solution-processed TADF-assisted Organic Light-Emitting Diodes
초록 The importance of thermally activated delayed fluorescence (TADF) materials in organic light-emitting diode (OLED) applications continues to grow as a consequence of their unique properties and excellent performance. Up to recently, various small molecule-based solution-processable TADF emitting materials have been researched, but polymer-based studies are still lacking. In this work, new green-emitting TADF polymer, P(DMTRZ-Cp) was designed and synthesized based on the structure of DMAC-TRZ as a well-known TADF small molecule. The 1,1-diphenylcyclohexane (Cp) moiety introduced into the structure of the polymeric emitter act not only as non-conjugated linker but also help enhancing solubility. P(DMTRZ-Cp) showed obvious TADF features and exhibited the maximum external quantum efficiency of up to 15.4 % with green emission by applying solution-processed TADF-OLED devices.
