The intermolecular

• (terpyridine)-derived oligopyridines (BTPs), are large polyaromatic molecules with C2v symmetry, are well established compounds, and are known to self-assemble [5] at the liquid/HOPG [6][7][8][9][10][11] and at the gas/solid interface [12][13][14]. Self-assembly also occurs under electrochemical conditions [15
