The porphyrin‐bridged cyclophane 1 was prepared in order to mimic monooxygenase activity and serve as a supramolecular catalyst for the hydroxylation of polycyclic arenes. In methanol, arenes such as anthracene, ace‐naphthylene, and phenanthrene are firmiy complexed in the nonpolar interior of 1 . In 2,2,2‐trifluoroethanol in the presence of iodobenzene, the iron(III) derivative 2 catalyzes the oxidation of acenaphthylene to ace‐naphthen‐1‐one (65% yield).
