Porphyrins have been widely recognized for their unique photo‐ and electrochemical properties as well as their crucial roles in a wide variety of biological processes including catalysis, oxygen transport, and photosynthesis. In addition, their size and predictable coordination geometries makes them attractive components in the assembly of functional supramolecular assemblies. Advances in porphyrin synthesis have enabled their incorporation into rotaxanes not only as stoppers but also as components of the macrocycle, or even higher order rotaxane architectures, each design imparting unique functionality either through redox, fluorescence, or coordination environment. Here we describe advances in the synthesis of increasingly complex porphyrin‐containing rotaxane assemblies and their dynamic properties that arise from the porphyrin inclusion.
