A novel lactam-based AIE building block for high-performance deep-blue electroluminescent materials
Abstract
excited-state properties, promote the formation of hybridized local and charge-transfer (HLCT) states, and activate hot-exciton channels in the electroluminescence process to harvest high-lying triplet excitons. Among these derivatives, PADP-TPA with triphenylamine modification exhibits a maximum external quantum efficiency (EQE) of 9.2% in a deep-blue OLED with CIE coordinates of (0.154, 0.049), representing state-of-the-art performance for OLEDs based on deep-blue AIE fluorescent materials. These results not only elucidate the structure-property relationships of the PADP building block but also demonstrate its significant potential for the design of highly efficient deep-blue OLED emitters.
