Abstract
. Furthermore, the electroluminescence spectra of Spiro-3TCzBN-based OLEDs show a notably stable profile as the doping level increases from 1 to 10 wt%. These results indicate that the conformational locking strategy is a compelling design approach for helicene, which is expected to be a potential chiral optical material for next-generation high-resolution CP-OLED displays.
