A chiral phthalocyanine dimer with well-defined supramolecular symmetry based on π-π interactions

Abstract

Cooperation is the name of the game: The first example of a chiral phthalocyanine dimer with well-defined supramolecular weight and symmetry formed through cooperative multiple π-π interactions among nine pairs of aromatic moieties between two chiral phthalocyaninato zinc molecules has been clarified (see figure).
