Various pathways towards corroles bearing additional donor sites especially those with diazacrown units have been evaluated. Macrocyclic diamidation based on the reaction of diamines with diesters was found to be the key step in the overall synthetic scheme. This strategy was applied successfully to the synthesis of three compounds possessing macrocyclic diamide or diamine moieties. In addition, a meso-picolyl derivatized corrole was prepared. The new ligands were investigated with respect to the regioselectivity of transition metal insertion. Mononuclear corrolates of copper and cobalt are formed as the only isolable products, if simple copper and cobalt precursors and standard metalation protocols are applied. The results prove, that corroles can be used as selectively coordinating building blocks in multi-compartment ligand systems with peripheral crown ether and pyridyl functionalization.

It has been known for a long time that electron irradiation induces damage in maximal valence transition metal oxides such as TiO2, V2O5, and WO3, of which transition metal ions have an empty d-shell. This type of damage is excited by electronic transition and can be explained by the Knoteck-Feibelman mechanism (K-F mechanism). Although the K-F mechanism predicts that no damage should occur in transition metal oxides of which the transition metal ions have a partially filled d-shell, namely submaximal valence transition metal oxides, our recent study on ReO3 shows that submaximal valence transition metal oxides undergo damage during electron irradiation.ReO3 has a nearly cubic structure and contains a single unit in its cell: a = 3.73 Å, and α = 89°34'. TEM specimens were prepared by depositing dry powders onto a holey carbon film supported on a copper grid. Specimens were examined in Hitachi H-9000 and UHV H-9000 electron microscopes both operated at 300 keV accelerating voltage. The electron beam flux was maintained at about 10 A/cm2 during the observation.
