Significance

A light-driven molecular mimic of a muscle fiber is presented. End-capped stilbene-containing α-cyclodextrin (αCD) dimers can be synthesized, in which the E-stilbene unit is contained in the hydrophobic pocket of the αCD. Upon irradiation, the E- to Z-isomerization of the stilbene unit causes the α-cyclodextrin to slide. This action leads to an overall contraction of the dimer, and the photoisomerization is reversible.
