Chiral amplification is an interesting phenomenon in supramolecular chemistry mainly observed in complicated systems in which cooperative effect dominate. Herein, chiral, supramolecular, propeller‐like architectures have been constructed through coassembly of an achiral disk‐shaped molecule and chiral amino acid derivatives driven by intermolecular hydrogen bonding. Both the “sergeants‐and‐soldiers”

Benzene-1,3,5-tricarboxamide (BTA) derivatives with one or three phenylalanine octyl ester (PheOct) moieties were synthesized and their supramolecular polymerization and chiral amplification behavior were investigated in mixing experiments between enantiomer pairs and in mixing with another, achiral BTA component. The incorporation of PheOct moieties is shown to have a major impact on the supramolecular self-assembly.
