Mentions: A different approach to the regulationof catalytic activity is via the addition of small molecules suchas ions, which can change the supramolecular structure of the catalyst,as is observed in many enzymatic processes. Mirkin and co-workersreported the synthesis of triple-layer complex 142 composedof two transition metal hinges, two chemically inert blocking exteriorlayers, and a single catalytically active interior Al (III)-salencomplex, which can act as a ring-opening polymerization catalyst forε-caprolactone (Figure 55). Polymer growth and molecular weight could be controlledby the addition of Cl– (catalytic layer exposed)or of the Cl– abstracting agent NaB(ArF)4, which results in the fully closed complex 142.1435−1437 Recently, the same research group reported an allosterically regulatedphotoredox catalyst based on a similar switching mechanism.1438
