Abstract
Achieving high circularly polarized electroluminescence (CP-EL) performance in organic light-emitting diodes (OLEDs) remains a significant challenge. In this study, chiral nematic liquid crystal polymers (LCPs) are co-assembled as chiral fluorescent materials by doping 1 wt% chiral binaphthyl-based R/S-D inducers into a LCP (P-PyP), displaying blue circularly polarized luminescence (CPL) signals (|glum| = 0.025, λem = 470 nm, ΦFL = 37%) after thermal annealing at 140 °C. Notably, the resulting chiral LCP films can serve as the emitting layer (EML) in non-doped OLEDs, and exhibit good CP-EL emissions (gEL = −0.019/+0.015, λEL = 484 nm). This work demonstrates a pathway for the high CP-EL performance materials through the chiral co-assembly of LCPs.
