H. Hori et al., EFFICIENT PHOTOCATALYTIC CO2 REDUCTION USING [RE(BPY)(CO)(3)(P(OET)(3))](+), Journal of photochemistry and photobiology. A, Chemistry, 96(1-3), 1996, pp. 171-174
[Re(bpy)(CO)(3){P(OEt)(3)}](+) (1(+)) (bpy, 2,2'-bipyridine) is the mo
st efficient homogeneous photocatalyst for the selective reduction of
CO2 to CO reported to date. Both the quantum yield and turnover number
of the photocatalytic reaction are strongly dependent on the irradiat
ion light intensity and wavelength because of the unusual stability of
the one-electron-reduced species [Re(bpy(.-))(CO)(3){P(OEt)(3)}] (1).
