Quinolinylmethanone-Based Thermally Activated Delayed Fluorescence Emitters and the Application in OLEDs: Effect of Intramolecular H-Bonding
Source abstract
Abstract
Three new quinoline TADF emitters, 2QPM-mDC, 2QPM-mDTC, and 4QPM-mDTC, were designed and synthesized and the emitters show ΔEST as low as 0.07 eV and high PL quantum yield (PLQY) up to 98%. An electroluminescence device based on 2QPM-mDTC can reach high EQE over 24%. Compared with the reported TADF devices, the device shows narrow emission bandwidth and high color purity. The excellent device performance is likely ascribed to the molecular design of 2QPM-mDTC containing an intramolecular H-bonding in the molecule.
