Introducing charge transfer functionality into prebiotically relevant β-sheet peptide fibrils.
Incorporation of naphthalene diimide moieties as side chains of short amphiphilic peptide results in the formation of fibrils that exhibit substantial intermolecular π-stacking interactions. These interactions can be manipulated without affecting the structure. The new system is suggested as a first step towards functional self-synthesizing materials.
