Irradiation with 470 nm light results in the near-quantitative switching to a monomeric species [Pd(Z-L)₂ ]²⁺ , which can be reversed by irradiation with 405 nm light, or heat. The photoswitching selectivity towards the metastable isomer is significantly improved upon self-assembly, and the thermal half-life is extended from 40 days to 850 days, a promising approach for tuning photoswitching properties.Angewandte Chemie (International ed. in English)Visible-Light-Responsive Self-Assembled Complexes: Improved Photoswitching Properties by Metal Ion Coordination.PMC9541570FT170100094DiNardi RGTajik MDonald WATian RBeves JEDouglas AOPrice JRfalseVisible-Light-Responsive Self-Assembled Complexes: Improved Photoswitching Properties by Metal Ion Coordination.A photoswitchable ligand based on azobenzene is self-assembled with palladium(II) ions to form a [Pd₂ (E-L)₄ ]⁴⁺ cage.
