Helical Colloidal Sphere Structures through Thermo‐Reversible Co‐Assembly with Molecular Microtubes

The co-assembly of spherical colloids and surfactant–cyclodextrin microtubes yields a library of dynamic colloid-in-tube structures, including helices. In situ observations of these structures, including their thermo-reversible assembly and disassembly, demonstrate the potential of the interplay between molecular and colloidal self-assembly, thereby providing a novel route to temperature-sensitive particle alignment and release.
