aMeasured in 4 : 1 v/v ethanol:methanol at room temperature. bThe emission spectra and emission lifetime were obtained by exciting into the lowest MLCT band in 4 : 1 v/v ethanol:methanol. cHalf-wave potentials assigned to the Ru3+/2+ couple for ruthenium sensitizers bound to nanocrystalline TiO2 film, measured in 0.1 M LiClO4 acetonitrile solution. dCalculated from E* (Ru3+/2+)) = E (Ru3+/2+) − E 0-0; E 0-0 values were estimated from the 5% intensity level of the emission spectra at 77 K. eData taken from [13]. |
