C₆₀ / Corannulene on Cu(110)
(Result of the month 12/2008)

The COR host lattice:
(a) STM image of a COR monolayer on Cu(110) revealing enantiomorphous a  and r  domains. High-symmetry directions of the Cu(110) surface (black arrows) and the close-packed directions of the COR lattice (white arrows) are indicated.
(b) Highresolution STM image revealing the bowl shape of COR.
(c) Structural model of the F-domain with molecular orientations as determined from XPD experiments.A 6° tilt of the C_5σ axis along the [110] direction causes a C-C bond between a C6 and the C5 ring (highlighted in yellow) being closest to the surface.
(d) Schematic illustration of the surface-supported COR host lattice, with some of the host sites occupied by fullerene C₆₀ guests.

Manipulating C₆₀ molecules away from their original positions by an abrupt reduction of the gap voltage from -1.2 V to -0.02 V during scanning.
a) STM image with normal tunnelling parameters after deposition of ~1 ML C₆₀ onto the COR host lattice at ET. The white arrow indicates the position where an abrupt reduction of the gap voltage is applied during the scanning.
b) After an abrupt reduction of the gap voltage, some C₆₀ molecules were swept away and small C₆₀ vacancy islands ("B”) were created. This tip created C₆₀ vacancy islands ("B”) has an identical apparent depth as the original one ("A”) with respect to the C₆₀ aggregates, suggesting that the C₆₀ molecules are directly located on top of underlying COR bowls.
