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.
