Characterization of porphyrin supramolecular complexes using NMR diffusion spectroscopy

The usefulness of diffusion ordered NMR spectroscopy (DOSY) as a characterization technique for systems that are non-covalently associated in solution is demonstrated. This study investigated the diffusion properties of a series of porphyrin-based building blocks and host materials which culminated in the characterization of a self-assembled porphyrin-containing capsule.
