Multi‐shell Soft Nanotubes from Cyclic Peptide Templates

Multi-shell nanotubes containing poly(acrylic acid) external shell and polyisoprene internal shells are prepared by exploiting the self-assembly of an alt-(d,l) cyclic peptide template. Crosslinking of the acrylic acid shell, followed by ozonolysis of the polyisoprene, gives access to nanotubes with an internal pore which can be controlled by the degree of polymerization of polyisoprene.
