1 Introduction Metal complexes with a d 6 $$ {d}^6 $$ electron configuration exhibit rich excited state behavior through a combination of an electron-rich center, closely spaced d-orbitals, and a shell of stabilizing and electron-accepting ligands. One of their most intriguing properties is the ligand-selective photodissociation under UV light, for instance, of a carbonyl ligand [1].
