The effect of pyrrole- and pyrrolidine-containing ligands (L) on the properties of heteroleptic [RuL(2)dcbpy](2+) complexes has been investigated. TiO2 electrodes modified with the new complexes exhibited extended absorption domains and high absorbances. Providing that a cobalt-based mediator was used for regeneration of the Ru-II state, good incident photon-to-current efficiency (near 80%) values were obtained in the pyrrole series.
