Bambus[n]urils (BUs, n = 4, 6) are a group of macrocyclic compounds consisting of repeating glycoluril units connected in an alternating manner by methylene bridges. BUs act as anion receptors, with the anion binding site located inside their electron-deficient cavity. They can form complexes with various inorganic as well as organic anions, both in organic solvents and in water.1,2 BUs have already been investigated for different purposes, including anion transmembrane transport,3 construction of ion-selective membranes,4 or formation of mechanically interlocked molecules.5 Nevertheless, their potential for development of new functional materials has been only scarcely studied. Therefore, we have focused our attention on development of materials consisting of BU macrocycles. In our own studies, we have utilised BUs for the modification of silica gel by a non-covalent deposition on its surface or through covalent bonds.6 The ability of these materials to extract anions from water has been explored, with a particular emphasis on the uptake of dicyanoaurate(I) as an industrially relevant anion. Furthermore, supramolecular assemblies based on BUs, such as metal-organic frameworks (MOFs) and metal-organic gels (MOGs), have been investigated for their potential application in water remediation or catalysis. Using BUs to design anion-responsive materials, thereby merging supramolecular chemistry approaches with materials science, brings new opportunities to explore systems where anions play a crucial role.
