Polycyclic aromatic hydrocarbon-based nanocars equiped with triptycene wheels — Henri-Pierre Jacquot de Rouville^1,2,4, Claire Kammerer^1,2, Corentin Durand^1,2, •Christian Joachim^1,2,3, and Gwénaël Rapenne^1,2 — ¹Université Paul Sabatier, Toulouse, France — ²GNS, CEMES-CNRS, Toulouse, France — ³International Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science (NIMS), Namiki Tsukuba, Ibaraki, Japan — ⁴Present adress : ITODYS-CNRS, Université Paris Diderot, Paris, France

Technomimetic molecules[1] are molecules designed to imitate macroscopic objects at the molecular level, also transposing the motions that these objects are able to undergo. We designed and synthesized two nanocars including triptycene wheels in an extended aromatic platform as a cargo zone[3].

However, the manipulation of the planar one on metallic surfaces proved to be difficult due to a strong molecule-surface interaction, the curved nanocar adress this problem by decreasing the interaction between the aromatic system and the surface. STM experiments are currently underway to test the molecule before the nanocar race organized next spring in Toulouse, France.
