Abstract

Rotaxanes are mechanically interlocked molecules consisting of a ring kept around a linear thread by two "stoppers" at the ends. Rotaxane-based devices include light-driven molecular pistons and molecular motors. We use 2D-IR spectroscopy to study rotaxanes composed of a benzylic amide-based ring hydrogen-bonded onto a succinamide-based thread. By determining the coupling between the carbonyl groups in the ring and the thread from the 2D-IR spectrum, the solution conformation of the ring-thread system can be probed. Fluctuations in the length of the hydrogen bonds between ring and thread are observed by measuring time-delayed spectra.

 

This lecture is part of the MSC mini-symposium New developments in two-dimensional infrared spectroscopy. Please pre-register with Margriet Derix if you wish to attend one or more of its three lectures.
