  text: In the search for noble metal free photocatalytic systems, iron is the dream
    candidate. To increase excited state lifetimes of iron complexes, the multichromophoric
    approach is promising, combining organic chromophores with photoactive iron complexes,
    potentially enabling a reservoir effect. We present a series of chromophore-functionalized
    complexes based on the parental FeIII complex [Fe(ImP)2][PF6] (HImP = 1,1′-(1,3-phenylene)bis(3-methyl-1-imidazole-2-ylidene)).
    The four organic chromophores benzene, naphthalene, anthracene, and pyrene are
    attached to the ImP-ligand in para-position to the coordination site to systematically
    investigate the influence of the steric demand and electronic properties of the
    chromophore on charge transfer lifetimes as well as photodynamics. A thorough
    ground state characterization was conducted in addition to investigations of the
    excited state dynamics by transient absorption spectroscopy and streak camera
    emission measurements. The conclusions drawn are supported by extensive DFT calculations.
    The emission coefficients could be significantly improved by the addition of chromophores.
    After excitation of the complexes with larger chromophores, coplanarization of
    the backbone and complex motif occurs to stabilize the formal charge. This results
    in population of a superligand state that exhibits a much faster radiationless
    relaxation to the ground state compared to the parent complex, hindering a reservoir
    effect.
