Long-Range Chiral Induction by a Fully Non-Covalent Approach in Supramolecular Porphyrin-Calixarene Assemblies†.

The hierarchical assembly, in aqueous solution, of a new multi-metalloporphyrin/calixarene aggregate has been accomplished. In this supramolecular system transfer of chirality, from the outermost components to the central porphyrin reporter, takes place as a result of favorable and fully noncovalent long-range electronic communication.
