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.},
