Observations on the low-energy limits for metal-to-ligand charge-transfer excited-state energies of ruthenium(II) polypyridyl complexes.
The 77 K emission spectral maxima of bis(bipyridine)ruthenium(II) complexes are found to approach a limit at energies below about 14,000 cm(-1). There is also evidence for related low-energy excited-state limits in some other classes of ruthenium polypyridyl complexes. The shapes of the vibronic sidebands found in these limits differ from those of complexes that emit at higher energies. These l...
متن کاملTime-resolved spectroscopy of the metal-to-metal charge transfer excited state in dinuclear cyano-bridged mixed-valence complexes.
Visible pump-probe spectroscopy has been used to identify and characterize short-lived metal-to-metal charge transfer (MMCT) excited states in a group of cyano-bridged mixed-valence complexes of the formula [LCo(III)NCM(II)(CN)(5)](-), where L is a pentadentate macrocyclic pentaamine (L(14)) or triamine-dithiaether (L(14S)) and M is Fe or Ru. Nanosecond pump-probe spectroscopy on frozen solutio...
متن کاملPhotochemistry and electron-transfer mechanism of transition metal oxalato complexes excited in the charge transfer band.
The photoredox reaction of trisoxalato cobaltate (III) has been studied by means of ultrafast extended x-ray absorption fine structure and optical transient spectroscopy after excitation in the charge-transfer band with 267-nm femtosecond pulses. The Co-O transient bond length changes and the optical spectra and kinetics have been measured and compared with those of ferrioxalate. Data presented...
متن کاملUltrafast Dynamics in the Metal-to-Ligand Charge Transfer Excited-State Evolution of [Ru(4,4′-diphenyl-2,2′-bipyridine)3]
The transition metal complexes [Ru(dmb)3] and [Ru(dpb)3], where dmb is 4,4′-dimethyl-2,2′-bipyridine and dpb is 4,4′-diphenyl-2,2′-bipyridine, have been studied by femtosecond visible electronic absorption spectroscopy. Spectroelectrochemical measurements in conjunction with nanosecond time-resolved absorption spectroscopy allow for the assignment of various features in the excited-state differ...
متن کاملMETAL-METAL CHARGE TRANSFER IN LnM-CN-FeCl3 COMPLEXES
By combining the organometallic cyanides L n M-CN [L n M = Cp(dppe)Fe, Cp(dppe)Ru, Cp(PPh 3 ) 2 Ru] with FeCl 3 the dinuclear complexes L n M-CN-FeCl 3 were obtained. Structure determinations have revealed configurations close to linear arrays Fe-C-N-Fe and Ru-CN-Fe. From the n(CN) band positions in their IR spectra it can be concluded that FeCl 3 is a very strong electron acceptor. Accordingly...
