A new record excited state 3 MLCT lifetime for metalorganic iron( ii ) complexes
Résumé
Herein we report the synthesis and time-resolved spectroscopic characterization of an homoleptic Fe(II) complex exhibiting a record 26 ps 3 MLCT lifetime promoted by benzimidazolylidene-based ligands. Time Dependent Density Functional molecular modeling of the triplet excited state manifold clearly reveals that, at equilibrium geometries, the lowest 3 MC state lies higher in energy than the lowest 3 MLCT one. This unprecedented energetic reversal in iron complexes series, with the stabilization of the charge-transfer state, opens new perspectives towards iron made excitonic and photonic devices, hampering the deactivation of the excitation via metal centered channels.
