Functionalization and Metal Ion Encapsulation Within a Triaxial Supramolecular Weave

Angewandte Chemie, EarlyView.
The functionalization of a triaxially woven supramolecular weave was achieved. Pre‐assembly modification of the peptide‐perylene monoimide building block enabled facile and homogeneous introduction of acetyl, pivaloyl and thiophene moieties throughout the assembly without disrupting the woven structure.
