Manipulation of tolyl-terpy molecules along the Au(111) reconstruction — •Rémy Pawlak1, Tobias Meier1, Marcin Kisiel1, Antoine Hinaut1, Thilo Glatzel1, Catherine Housecroft2, and Ernst Meyer1 — 1University of Basel, Department of Physics, Klingelbergstr. 82, CH-4056, Basel, Switzerland — 2University of Basel, Department of Chemistry, Spitalstrasse 51, CH-4056, Basel, Switzerland
In spring 2017, the first international ''NanoCar Race'' will be held in Toulouse (France) in a unique low-temperature ultra high vacuum four-probe scanning tunneling microscope. During the competition, the participants will have to simultaneously drive their vehicles over 100 nm along the Au(111) herringbone structure, only using electron injections from one of the STM tips. Here, we report on the adsorption characteristics and first driving experiences of the 4'-(4-Tolyl)-2,2':6',2''-terpyridine, so-called Swiss Nano Dragster on gold [1]. We show that our molecule is translated in a controlled way and high directionality through appropriate electrical excitation. We also find that peculiarities of the gold reconstruction can irremediably trap the molecules and reached a maximum speed of about 20 nm/hour.
