      abstract     = {Developing effective and versatile photocatalytic systems
                      is of great potential in solar energy conversion. Here we
                      investigate the formation of supramolecular catalysts by
                      electrostatic self-assembly in aqueous solution: Combining
                      positively charged porphyrins with negatively charged
                      polyelectrolytes leads to nanoscale assemblies where, next
                      to electrostatic interactions, π–π interactions also
                      play an important role. Porphyrin diacid-polyelectrolyte
                      assemblies exhibit a substantially enhanced catalytic
                      activity for the light-driven oxidation of iodide.
                      Aggregates with the hexavalent cationic porphyrin diacids
                      show up to 22 times higher catalytic activity than the
                      corresponding aggregates under neutral conditions. The
                      catalytic activity can be increased by increasing the
                      valency of the porphyrin and by choice of the loading ratio.
                      The structural investigation of the supramolecular catalysts
                      took place via atomic force microscopy and small angle
                      neutron scattering. Hence, a new facile concept for the
                      design of efficient and tunable self-assembled
                      photocatalysts is presented.},
