Abstract

A narrowband blue CP-TADF emitter with a rigid hetero-helicene structure (QAO-PhCz) was synthesized and characterized. QAO-PhCz exhibits good electroluminescence performance (EQE = 14.0%) and narrow FWHM. The enantiomers of QAO-PhCz display CPL and CPEL properties with |g_lum| and |g_EL|values of up to 1.1 × 10⁻³ and 1.5 × 10⁻³, respectively.
