The photoinduced electron transfer between the zinc porphyrin and the quinone unit of the U‐shaped host 1 (R = t Bu) is accelerated by an aromatic guest molecule complexed within its cavity. This rate enhancement is due to through‐space electron transfer across the interspaced guest. This process mimics the proposed behavior of some aromatic protein residues in certain photosynthetic centers.
