A new volume in the "Perspectives in Supramolecular Chemistry" series focusing on separating supramolecular structures, a key step in supramolecular chemistry. Two guest editors have been at the forefront of the development of chromatographical methods to deal with supramolecular systems. Reactions of supramolecular structures show the way into the future of chemistry. Fumio Toda is one of the driving forces in the development of supramolecular separation systems. A practical title in the prestigious “Perspectives in Supramolecular Chemistry” series.
