A series of bis(tridentate) cyclometalated oligopyridine complexes [Fe-II(C<^> N<^>N)(L)](+) have been synthesized via the reactions of [Fe-II(C<^> N<^>N-py)Br(PMe3)(2)] (1, HC<^>N-py<^>N-py = 6-(phenyI)-2,2′-bipyridine) and [Fe-II(C<^>N-ppy<^>N-isoquin)Br(PMe3)(2)] (2, HC<^>N-ppy<^>N-isoquin = 3-(4,6-diphenylpyridin-2-yl)isoquinoline with tridentate ligands L, affording [Fe-II(C<^>N-ppy<^>N-py)(4′-R-tpy)](+) (3a-e, R = H, Cl, p-ClC6H4, p-MeOC6H4, p-tol, respectively; tpy 2,2′:6′,2 ”-terpyridine), [Fe-II(C<^>N-ppy<^>N-isoquin)(tpy)](+) (4), [Fe-II(C<^>N-ppy<^>N-py)(6-(Ph2PCH2)-bpy)](+) (5, bpy = 2,2′-bipyridine), and [Fe-II(C<^>N-py<^>N-py)(6-NHC-bpy)](+) (6, NHC = N-heterocyclic carbene). Complexes 3-6 exhibit bathochromically shifted absorption bands, markedly cathodically shifted E-1/2 (Fe-III/Fe-II) values, and narrowed electrochemical band gaps in comparison to those of [Fe-II(tpy)(2)](2+), as revealed by UV-vis absorption spectroscopy and cyclic voltammetry. DFT and TDDFT calculation studies revealed strong mixing of MLCT with LLCT transitions as origins to the major absorption bands. Complex 6 incorporating a cyclometalating unit and an NHC donor exhibits panchromic absorption, and 5 shows markedly enhanced molar absorptivity in the visible region. A femtosecond transient absorption spectroscopic study of 6, coupled with DFT and TDDFT calculations and spectroelectrochemical measurements, gave evidence for the possible involvement of a (MLCT)-M-3 state with a lifetime of 21.4 ps.
