Relative to π-electron systems between elements from the second row of the periodic table, those between heavier main group elements should exhibit higher HOMO and lower LUMO levels. Moreover, such π-electron systems between heavier main group elements are expected to be good electron acceptors and donors, and they should also exhibit good electron transporting properties. With the ultimate goal to create unprecedented π-electron systems between heavier main group elements in mind, we designed d-π electron systems containing heavier main group elements in the π-electron moiety and transition metals in the d-electron moiety. In this account article, we present our recent progress on the generation of bimetallic ferrocenyl- and ruthenocenyl-based d-π electron systems containing π-bond spacers of heavier main group elements from group 14 or 15.
