Bambusuril Anion Receptors

Bambusurils are macrocyclic compounds whose synthesis was first reported in 2010. Since then bambusurils have been investigated mainly because of its six-membered homologues’ outstanding binding affinities towards inorganic anions in both organic solvents and water. Here we summarize the most important aspects of bambusuril chemistry. Basic characteristics of bambusurils are presented, followed by details of their synthesis, and a discussion of their supramolecular properties, with an emphasis on binding in water. Potential applications of bambusurils are highlighted at the end of the review.
