catenanes provide a novel backbone for constructing functional materials with unique structural characteristics. In this study, the novel photoswitchable [n]rotaxanes 11 and 12 based on dithienylethene unit were efficiently synthesized by the classical template-directed clipping approach. And their structures were well-confirmed by NMR, MS and elemental analysis. Investigation on photochromic properties indicated
