A filling that makes the sandwich : Large aromatic molecules are sandwiched by two π‐conjugated ligands (L) that are joined together by six {(en)Pd} 2+ units (M; en=1,2‐ethanediamine; see picture; guest red, {(en)Pd} 2+ yellow, ligand blue). This host has an M 6 L 2 composition and is distorted by the concave shape of the ligand. Without a guest, it releases the distortion by forming the dimeric M 12 L 4 in a reversible fashion.
