Synergistic 3D π-π networks enforce persistent foldamer configuration with tunable full-color circularly polarized luminescence.

ABSTRACT: Achieving molecular chirality with enantiostability in purely π-conjugated foldamers remains a substantial challenge due to inherently weak π-π stacking interactions and facile racemization. Herein, we introduce a novel design strategy employing synergistic intramolecular 3D π-π stacking networks within a 1,8-diarylnaphthalene framework, enabling foldamers to exhibit extraordinary configurational stability. A systematic series of quinoxaline- and phenazine-based foldamers incorporating carbazole (CZ) and diphenylamine (DPA) donors were synthesized, with chiral configurations stabilized through complementary face-to-face and laterally offset π-π stacking interactions. Single-crystal X-ray analyses and computational studies confirmed the formation of complex intramolecular π-networks, provid
