Rotaxane molecules have attracted considerable interest because of their performance in molecular electronic devices and nanoscale data-storage media. Low-temperature scanning tunneling microscopy is used to investigate the structure and conductance of single H2 rotaxane molecules (see figure) on a buffered Au(111) substrate at 77 K.
