Spirobifluorene-based hole-transporting materials for RGB OLEDs with high efficiency and low efficiency roll-off

Chem. Sci., 2024, Accepted Manuscript DOI: 10.1039/D4SC04979A, Edge Article Qian Li, Yusong Guo, Jingbo Lan, Yudong Yang, Di Wu, Zhengyang Bin In this work, we designed and synthesized three spirobifluorene (SBF)-based hole-transporting materials (HTMs) by incorporating the di-4-tolylamino group at different positions of the SBF skeleton. These materials demonstrate excellent thermal...
