Abstract
Multi-responsive and optically-active diarylethene (DAE)-based [2]pseudo-rotaxane polymers were prepared <italic>via</italic> host–guest interactions of Zn<sup>2+</sup> coordinated with two terpyridyl ligands bearing crown-ethers as an energy donor host and DAE containing two ammonium salts as an acceptor guest.
