Abstract
Inspired in the organic macrocycles cucurbituril and hem-cucurbituril, bamabusuril (BU6) was synthesized in 2010 from the condensation of 2,4-dimethylglycoluril and formaldehyde in HCl, where Cl- anions act as cyclization templates. Its structure reminds cucurbituril, which is also formed by 6 units glycolurilic monomers, but it is less rigid and displays a huge affinity for anions, just …
