Supramolecular Light-Harvesting Antennas of Metal-Coordinated Bis(8-Hydroxyquinoline)-Substituted Porphyrin Networks. 
Artificial antenna complexes of metal-coordinated bis(8-hydroxyquinoline)-substituted porphyrin networks that mimic antenna chromophores in plants were organized on titanium dioxide electrodes in photoelectrochemical cells.  The generated photocurrents can be optimized according to the two ways of porphyrin self-assembly due to the "antenna effect": changing the number of assembled porphyrin monolayers and the number of generations of the metal-coordinated porphyrin networks.
