Artificial molecular-level machines. Dethreading-rethreading of a pseudorotaxane powered exclusively by light energy.
The reversible light-driven dethreading-rethreading of a pseudorotaxane is obtained in solution by exploiting the (E)-(Z) photoisomerisation of azobenzene, and monitored through fluorescence signals.
