Design and photophysical investigation of highly efficient pyrene-substituted acridone blue emitters for OLED applications

Abstract

Development of the new fully organic emitters remains one of the major challenges in organic electronics.Acridone derivatives have previously demonstrated high EL efficiency, excellent color purity, and low roll-off in OLED devices. Meanwhile, pyrene derivatives are known to form excimers, exhibiting broad blue emission in the 450-470 nm region. Inspired by these features, we designed three new pyrene-substituted acridone derivatives as potential deep-blue TTA-emitters, synthesized and studied their photophysizal properties. Results demonstrate that pyrene-substituted acridones represent promising platform for the developments of efficient blue-emitting materials and provide basis for future structural optimization.
