Cover Feature: Excited‐State Kinetics of an Air‐Stable Cyclometalated Iron(II) Complex (Chem. Eur. J. 51/2019)

Iron as substitute for noble metals in photoactive compounds is a desired aim in photochemical research. By development of a new synthesis route, the first photophysical characterization of cyclometalated iron(II) complexes could be achieved. In comparison to the related complex, [Fe(tpy)2]2+, without a cyclometalating ligand, the lifetime of the photochemically relevant MLCT state could be increased by a factor of 5.5. With the results summarized in the cover, the lack of experimental data on such complexes could be eliminated and the way to a new ligand design strategy was opened.
