Summary:Heteroleptic copper( i ) bis(phenanthroline) complexes with surface anchoring carboxylate groups have been synthesized and immobilized on nanoporous metal oxide substrates. The species investigated are responsive to the external environment and this work provides a new strategy to control charge transfer processes for efficient solar energy conversion. The ground- and excited-state properties of redox- and photo-active Cu( i ) complexes immobilized in nanoporous AAO are responsive to pore diameter.
