text: Since adenine only has one functional amino group that is available for anchoring the molecule to the substrate, and the existence of a more aromatic ring favors stronger π-substrate interactions [ 5 ], therefore, adenine tends to lie flat at most metal surfaces with H-bonding as the dominant inter-molecular interaction, whereas other nucleobases such as cytosine and guanine have both oxo and amino groups that tend to interact with copper more strongly, which lead to almost upright-molecular orientations with the formation of ordered molecular assemblies driven by dispersion interactions [ 32 ].
