Abstract
Supramolecule systems, which show photoinduced electron or energy transfer, are promising for application in construction of photosynthetic reaction center and molecular electronic devises. Toward developing such systems, fullerenes attract the attention as electron acceptors because of their specific structures and properties. The construction of various non-covalently linked donor-acceptor systems based on pyridine functionalized C60 fullerene derivatives and metal porphyrins have been reported. On the other hand, endohedral metallofullerenes have higher electron-accepting ability and form more stable anions compared to the empty fullerenes.
Recently, we have investigated the complexation behavior of the endohedral metallofullerene ligands with the organic molecules by electron transfer between them. The facile electron transfer is characteristic of endohedral metallofullerenes.
In this work, we focused on the paramagnetic metallofullerene La@C82 and investigated the interaction between the paramagnetic endohedral metallofullerene ligand and fused zinc porphyrin dimer in toluene.
