Synthesis and Copper(I)‐Driven Disaggregation of a Zinc‐Complexed Phthalocyanine Bearing Four Lateral Coordinating Rings

A new zinc phthalocyaninate, bearing four flexible phenanthroline‐containing 30‐membered rings was synthesized by template condensation of a macrocyclic phthalonitrile. The resulting phthalocyanine was an insoluble aggregate. However, in the presence of CuI ions, the formation of a soluble complex was observed. UV/Vis and DOSY NMR spectroscopic studies showed a monomolecular state for this species in solution. 1H‐1H ROESY demonstrated that the macrocyclic substituents adopt a folded conformation, giving the complex a globular shape. The folding originates from stacking interactions between the phthalocyanine core and peripheral copper(I)–phenanthroline complexes.
