Stable submicrometer‐sized hollow spheres of bola‐form amide (see Figure) are formed in aqueous solution via non‐covalent interactions induced by the presence of a hydrophilic substrate. Rod‐like micelles self‐assemble to form spherical vesicles, which, in the presence of the substrate, gather to form spherical hollow particles. In contrast, when no substrate is present, the spherical vesicles to self‐assemble into fibers.
