A study of self-assembled 1,8,13-tris(mercaptomethyl)-triptycenes (TMMT) on Ag(111) was carried out. Experimental and simulated STM images showed a threefold protrusion attributable to the upright oriented TMMT molecule, which self-assembles into two packing configurations. Preference of highly ordered structures suggests a substantial degree of intermolecular interactions. DFT calculations reveal that triptycenes, methylene bridges, and thiols are responsible for the intermolecular interaction, chirality, and substrate interaction respectively. This work reveals intermolecular interactions between three-dimensional molecules, in which the interacting forces are not confined to a single plane.
