Tuning the rates of long-range charge transfer across phenylene wires.
Walking a tight wire: Phototriggered charge transfer across a tetra-p-dimethoxybenzene bridge is three orders of magnitude faster than that across a structurally similar tetra-p-xylene spacer, despite equal reaction driving forces in both cases [picture: see text]. This result is interpreted in terms of markedly different donor-bridge energy gaps.
