3. Second-generation molecular shuttles

3.1 Wider, faster

The study of other copper-based molecular machines has revealed that one of the critical factors influencing the speed of their movements is steric hindrance around the complexation sites . Thus, when a polypyridine ligand is functionalized on the positions adjacent to the nitrogen atoms, this considerably reduces the decomplexation speed, or "unhooking", of the unstable complexes and thus delays the machine's setting in motion.
