Abstract
Control of chiral assembly across length scales is desirable but challenging. Herein, we demonstrate controllable construction of microscopic chiral twists through hierarchical assembly of enantiomeric styrylpyridinium-derived glutamide amphiphiles (L/D-SPG). By combining variable-temperature spectroscopy with in-situ real-time optical microscopic observation, the dynamic chirality transfer process across spatial and length scales during assembly is elucidated. It is revealed that hydrophobic interactions between alkyl chains and intermolecular hydrogen bonds dominate the initial assembly of SPG oligomers, which subsequently elongate into microscopic twists through synergistic action of multiple non-covalent…
