Slim guests are welcome: Aromatic macrobicyclic amphiphiles underwent self-assembly through a face-to-face interaction to form dimeric micelles, which further associated laterally to form porous sheets with nanometer-sized pores. The resulting sheets efficiently intercalated planar aromatic guest molecules, whereupon the porous sheets were reversibly transformed into closed sheets (see picture).
