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 (see picture). This result is interpreted in terms of markedly different donor–bridge energy gaps.
