Conventional photosensitizers for photocatalysis are usually based on precious metals. Therefore, there is a desire to replace them with first-row transition metals. Iron based photosensitizers are promising candidates, but have only short lived charge transfer states. Targeted ligand design is used to address this problem. This talk presents a series of luminescent iron(III)-complexes with modified ligands. The findings are derived from time-resolved techniques, namely femtosecond transient absorption UV-Vis spectroscopy and streak camera measurements. The results are thoroughly examined in the context of electronic relaxation dynamics, shedding light on the intricate processes governing the observed phenomena.
