Back Cover: Supramolecular Velcro for Reversible Underwater Adhesion (Angew. Chem. Int. Ed. 11/2013)
Underwater supramolecular velcro exhibiting strong and reversible adhesion was achieved using a synthetic ultrahigh-affinity host–guest binding pair of cucurbituril (CB) and aminomethylferrocene (Fc). In their Communication on page 3140 ff., K. Kim et al. show that the CB loops and Fc hooks anchored on different surfaces adhere robustly under water without the need for curing agents, and the adhesion is mechanically and chemically reversible.
