Despite the remarkable progress made in the construction of nano and microscale architectures with welldefined sizes and shapes by selfassembly, a selforganizationbased synthesis of hollow toroids has so far proved to be elusive.  Here, we report the first such synthesis using rectangular, flat and rigid core monomers with anisotropically predisposed alkene groups which are crosslinked with each other by dithiol linkers using thiolene photopolymerization to create the hollow toroids.  The resulting superstructures are shapepersistent and mechanically robust in solution.  In addition, their size can be tuned by controlling the initial monomer concentrations, an observation which is supported by a theoretical analysis.  These hollow microrings can encapsulate guest molecules in the intratoroidal nanospace and act as templates for circular arrays of metal nanoparticles on their peripheries.
