Abstract
Recent results regarding the importance of tunneling-barrier heights for charge transfer between distant redox partners are reviewed. Examples include studies of photoinduced hole transfer in donor-bridge-acceptor systems, as well as work on mixed valence molecules. The barrier heights imposed by different bridging units are discussed. Key examples include the comparison of biphenyl and fluorene spacers, and the comparison of p-xylene and p-dimethoxybenzene bridging units. (C) 2011 Elsevier B.V. All rights reserved.
