Adsorption and Self‐Assembly of C70 Molecules at the Au(111)/n‐Tetradecane Interface: A Scanning Tunneling Microscopy Study

An STM study of C70 (sub‐)monolayers deposited at an n‐tetradecane/Au(111) interface (see Figure) is reported. The adsorption of C70 and C60 are compared in the light of their geometric and electronic differences. While C60 is a strained spherical cage, C70 has a reduced symmetry and an ellipsoidal shape. The structural differences between the C60 and C70 (sub‐)monolayers are discussed in terms of commensurability between the adsorbate and the Au (111) lattices.
