Abstract

Supramolecular structures were produced by in situ enzymatic condensation of Fmoc–Phe–(4-X), where X denotes electron withdrawing or donating groups, with Phe–NH₂. The relative contribution of π-stacking and H-bonding interactions can be regulated by the nature of X, resulting in tuneable nanoscale morphologies.
