摘要：

Combining strong sigma-donating N-heterocyclic carbene ligands and pi-accepting pyridine ligands with a high octahedricity in rigid iron(II) complexes increases the (MLCT)-M-3 lifetime from 0.15 ps in the prototypical [Fe(tpy)(2)](2+) complex to 9.2 ps in [Fe(dpmi)(2)](2+)1(2+). The tripodal CNN ligand dpmi (di(pyridine-2-yl)(3-methylimidazol-2-yl)methane) forms six-membered chelate rings with the iron(II) centre leading to close to 90 degrees bite angles and enhanced iron-ligand orbital overlap.
