Determine properties of functional catenanes and rotaxanes

To study molecular motors in the gas phase, we employed laser desorption in combination with supersonic expansions to obtain isolated, vibrationally and rotationally cold molecules. We have shown that it is possible to seed these supramolecular systems with molecular weight above 1,000 intact into a supersonic beam expansion.

To fully investigate the structural and spectroscopic properties of these molecular systems, a combination of high-resolution spectroscopic techniques have been used, REMPI to obtain the mass-selected vibrational resolved excitation spectra, UV-UV hole-burning to identify the different conformers and IR Ion-Dip spectroscopy to characterize these conformers.

From these experiments we have been able to determine the influence of the macrocycle on the conformational phase space accessible to the thread.
