Abstract

original image

Ein supramolekularer Klettverschluss mit bemerkenswerter mechanischer und chemischer Reversibilität und hervorragender Adhäsion wurde auf der Basis von multivalenten Wirt-Gast-Anordnungen erhalten (siehe Schema). Mit Cucurbit[7]uril (CB[7]) als Wirtspezies und Aminomethylferrocenyl (Fc) als Gastspezies funktionalisierte Siliciumoberflächen (blau) halten wegen der außerordentlichen Affinität dieser Komponenten unter Wasser zusammen.
