Merging dynamic and static chirality in propeller-shaped carbazole oligomers <i>via</i> chiral amine substitution.

ABSTRACT: Organic emissive materials exhibiting circularly polarized luminescence (CPL) have attracted considerable attention as promising candidates for next-generation photonic and electronic devices. However, most CPL-active molecules require laborious procedures such as asymmetric synthesis or optical resolution. In this study, chiral propeller-shaped molecules were conveniently synthesized by introducing chiral amines possessing static chirality into a dynamically chiral propeller framework. The molecule was obtained via a two-step aromatic nucleophilic substitution (S_NAr) sequence and exhibited distinct CPL activity (|g _lum| ≈ 2.0 × 10^-3 at room temperature) without optical resolution. Furthermore, a bifunctionalized derivative employing a chiral
