Reduction of CO2 to CO was efficiently photocatalyzed by [Re(4,4‘-X2bpy)(CO)3PR3]+ (X = H, Me; PR3 = P(OEt)3, P(O-i-Pr)3) in quantum yields of 0.16−0.20. Complexes with CF3 as X or trialkylphosphine as PR3 have much lower photocatalytic ability.

Time-resolved infrared spectroscopy of excited states of transition metal species
Autor: Michael W. George, James J. Turner, Frank P. A. Johnson, Jeremy R. Westwell
Publikováno v: Coordination Chemistry Reviews. 125:101-114
This article describes examples of the application of time-resolved infrared Spectroscopy (TRIR) to the probing of the excited states of transition metal species. Other “direct” methods for excited states include time-resolved absorption Spectros

Electron distribution in the excited state of [(OC)5W(4,4′-bipy)W(CO)5](4,4′-bipy = 4,4′-bipyridyl) determined by time-resolved infrared spectroscopy
Autor: James Turner, Michael W. George, Jeremy R. Westwell
Publikováno v: J. Chem. Soc., Dalton Trans.. :2217-2219
Employing fast time-resolved infrared (TRIR) spectroscopy, the pattern of the ν(CO) IR bands in the lowest excited state of [(OC)5W(4,4′-bipy)W(CO)5](4,4′-bipy = 4,4′-bipyridyl) shows that the electron distribution in this state is localised o
