The tubular secondary structure of a folded helical polymer—a poly(m-phenyleneethynylene) derivative carrying multiple cinnamate moieties—is stabilized by intramolecular cross-linking through topochemically controlled photodimerizations (see schematic representation). This approach should enable the generation of organic nanotubes with controlled dimensions and surface functionality that constitute attractive building blocks for functional nanostructures.
