Abstract

original image

Six packs: Hydrogen-bonded pyrogallol[4]arene hexameric nanocapsules self-assemble into spheres (A; see picture), tubules, and combinations of both (B) on the sub-micron scale. These assemblies were characterized by using dynamic light scattering, scanning electron microscopy, transmission electron microscopy (see inset), and atomic force microscopy techniques.
