• herringbone reconstruction indicating that the molecule–substrate interaction is of considerable extent. Investigations concerning the electronic structure of Er3N@C80/Au(111) reveals spatial variations dependent on the termination of the Au(111) at the interface.

• conformations was demonstrated for Sc3N@C80 [6]. Furthermore, the magneto-optically active endohedral fullerene Er3N@C80 permits a direct non-cage-mediated optical interaction with the incarcerated Er3+ ion in near-infrared that might make its use as optical manipulable fullerene-qubit possible [7][8][9].
