A 1,1′‐binaphthyl‐based bis(pyridine) ligand ( 1 ) was prepared in racemic and enantiomerically pure form to study the formation of [Pd 2 ( 1 ) 4 ] complexes upon coordination to palladium(II) ions with regard to the degree of chiral self‐sorting. The self‐assembly process proceeds in a highly selective narcissistic self‐recognition manner to give only homochiral supramolecular M 2 L 4 cages, which were characterized by ESI‐MS, NMR, and electronic circular dichroism (ECD) spectroscopy, as well as by single‐crystal XRD analysis.
