Since our discovery of 9,10-dithioanthracene1 as the first molecule that violates the substrate symmetry in its diffusive motion by perambulating along a single axis on a six-(three-)fold symmetric Cu(111) surface, we have explored this phenomenon extensively and applied it to: (a) transport of cargo,2 (b) probing of fundamental principles of physics and chemistry, and (c) multi-pronged efforts towards realization of this phenomenon at higher temperatures have been undertaken.
