Cyclic tetra-β-peptides (CP4s) and a bis-CP4 were synthesized to prepare peptide nanotubes (PNTs) by molecular stacking of cyclic peptides. The addition of bis-CP4 to the PNT preparation afforded PNT bundles increasing the direct and converse piezoelectiric coefficients, which is ascribable to bis-CP4 stapling PNTs into the parallel alignment of PNT dipoles.
