Controlling the Photophysical Properties of a Series of Isostructural d⁶ Complexes Based on Cr⁰, Mn^I, and Fe^II.

ABSTRACT: Development of first-row transition metal complexes with similar luminescence and photoredox properties as widely used Ru^II polypyridines is attractive because metals from the first transition series are comparatively abundant and inexpensive. The weaker ligand field experienced by the valence d-electrons of first-row transition metals challenges the installation of the same types of metal-to-ligand charge transfer (MLCT) excited states as in precious metal complexes, due to rapid population of energetically lower-lying metal-centered (MC) states. In a family of isostructural tris(diisocyanide) complexes of the 3d⁶ metals Cr⁰, Mn^I, and Fe^II, the increasing effective nuclear charge and ligand field strength allow us to control the energ
