Influence of Transition-Metal Ions on the Photoisomerization of a Pentadentate Azopyridine Ligand: Interplay of Charge-Transfer and Metal-Centered States
The influence of ZnII, FeII, and CoIII metal centers on the photoisomerization of a pentadentate azopyridine ligand, a potential scaffold for ligand-driven light-induced spin change (LD-LISC) systems, is investigated. Steady-state UV–vis and NMR spectroscopy reveal a systematic increase in the cis-isomer fraction in th...
