Self‐Assembly of Chemically Programmed Amphiphiles into Aqueous Nanotubes with a Lipophilic Lumen

The creation of complex hollow nanostructures with precise control over size and shape represents a great challenge in supramolecular soft materials. Here, we have further developed a bioinspired methodology for the formation of aqueous nanotubes of well‐defined dimensions and pore coating through the self‐assembly of amphiphiles that are chemically programmed with complementary nucleobases. These nanotubes are endowed with a hydrophobic lumen, whose diameter can be expanded as a function of the monomer length, in which apolar dyes can be efficiently encapsulated. Novel nanotubes of ca. 4 nm in diameter self‐assembled in water from custom‐tailored amphiphiles are able to selectively encapsulate apolar molecules within their lipophilic lumen.
