Two photons are better than one: A square-planar PtII complex with derivatized pyridine ligands was synthesized (see scheme), which undergoes two-photon-induced ligand substitution with 600–740 nm light. Linear and quadratic density functional response theory allowed identification of the electronic transitions involved.
