A chemical workout: A dithiophene rotaxane and its reference dumbbell were synthesized by means of aqueous Suzuki coupling (see scheme). The structure of this encapsulated dithiophene was confirmed by 1D and 2D NMR spectroscopy as well as molecular dynamics calculations. Photophysical properties of both systems were also investigated.
