The Dipolar Racer technical specifications

The American-Austrian NanoPrix Team has not yet selected the final racing molecule. They are still optimizing. Anyway, the strategy adopted is to propel the Dipolar Racer across a metal surface by virtue of the interaction between its dipole and the electric field present in the tunnel junction of a scanning tunneling microscope.

Synthesis of the Dipolar Racer

The Dipolar Racer is built using low adhesion molecular wheels, alkynyl axles, aryl chassis, and dipolar functionalities front and rear. Sonogashira cross coupling reactions are used to accomplish the assembly.

Team leader’s interview

What is the strong point of your NanoCar ?

It contains all parts of a car: Wheels, axles, chassis and - in particular - a dipolar unit to facilitate directional motion.

How did your team manage to achieve the synthesis ?

This has grown out of almost two decades in NanoCar research, so we have finally reached the point of competition.

How do you feel about the race:

This is an exciting time for nanotechnology and it represents the first of its kind to have nanotechnologies directly competing head-to-head. It is an exciting day for science and nanotechnology in particular that motivates us to improve the performance of our NanoCar.

After the race, what are your research perspectives:

Test and characterize further NanoCars, potentially light-driven structures.
