Nanostructural diversity: self-assembly of isomeric pyrene-cholane amphiphiles into sheets, tubes, and worm-like morphologies

Phosphodiester-linked cholane-pyrene-cholane trimers self-assemble into sheet-, tube- and worm-like nanostructures in aqueous conditions. The nanotubes and worm-like assemblies exist as single- or multi-walled objects. The supramolecular self-assembly of isomeric cholane-pyrene-cholane oligomers into different morphologies is described along as their spectroscopic properties.
