Visible-light-responsive self-assembled complexes: improved photoswitching properties by metal ion coordination

Authors

Abstract

A photoswitchable ligand based on azobenzene is self-assembled with palladium(II) ions to form a [Pd2(E-L)4]4+ cage. Irradiation with 470 nm light results in the near quantitative switching to a monomeric species [Pd(Z-L)2]2+. The assembled structures improve the selectivity of photoswitching towards the metastable isomer and increase its thermal lifetime.
