Abstract

The redox potential of a supramolecular porphyrin-phthalocyanine heterodimer was perturbed by the stacking of an extra metalloporphyrin to the phthalocyanine. This stacking gave rise to π-π and electrostatic interactions between the tetracationic dimer and the tetraanionic metalloporphyrin, with a Au(iii) metalloporphyrin exhibiting a larger effect than Cu(ii) and Pd(ii) complexes among square planar complexes.
