Abstract

original image

Lieblingsgast: Nahezu sechseckige Amphiphile ordnen sich in einer wässrigen Methanol-Lösung um sphärische hydrophobe Gastmoleküle zu tetraedrischen organischen Kapseln an (siehe Bild). In Gegenwart von Adamantan wandelt sich eine hexamere Kapsel aus solchen sechseckigen Amphiphilen in eine 1.7 nm große tetramere Kapsel um, die das Adamantan-Templatmolekül einschließt.
