Abstracts: Many second and third-row transition-metal complexes with d⁶ and d⁸ electronic configurations possess long-lived metal-to-ligand charge-transfer (MLCT) excited states, endowing them with excellent photochemical and photophysical properties. However, these metals are typically expensive and have a low abundance in the earth′s crust. Therefore, it is significant to develop inexpensive and high earth-abundant first-row transition-metal complexes as new photo-functional materials. Among them, Fe(Ⅱ) complexes with a 3d⁶ electronic configuration and Fe(Ⅲ) complexes with a 3d⁵ electronic configuration are the subject of particular interest. The main challenges are to modulate the MLCT excited state of Fe(Ⅱ) complexes through efficient ligand design and to achieve the ligand-to-metal charge transfer (LMCT) luminescence of Fe(Ⅲ) complexes. In recent years, significant progress were made in the studies of Fe(Ⅱ) complexes with relatively long MLCT excited-state lifetimes and Fe(Ⅲ) complexes with efficient LMCT luminescence. These complexes have been successfully applied in different aspects of photochemistry. This review summarizes the recent advances in modulating the excited-state properties of photofunctional Fe(Ⅱ) and Fe(Ⅲ) complexes, focusing on the molecular designs of metal complexes and ligands. In addition, the potential developments and applications in the photochemistry of Fe(Ⅱ)/Fe(Ⅲ) complexes are discussed.
