Further investigation into macrocyclic organometallic chemistry may entail the synthesis of analogous metallocenoporphyrins utilizing a range of metallocenes and 21carba-23-heteroporphyrins as fundamental building subunits. The feasible interplay between two metal cations locked in the firm molecular architecture offers a novel route for organometallic and metallocene-focused investigations, combining the benefits of metallocene and carbaporphyrin strategies.
