Graphical Abstract

A rigid rotaxane based on dithiophene and β-cyclodextrin (CD), as shown in the cover picture, and its shape-persistent corresponding dumbbell are discussed by L. Zalewski, D. Beljonne, H. L. Anderson, F. Cacialli, P. Samorì et al. in their Full Paper on page 3933 ff. In addition to the synthesis and characterization of both systems, they have elucidated the excited-state dynamics and the effect of cyclodextrin encapsulation, as well as finding that β-CD is a very mobile macrocycle.
