The quenching of the fluorescence of the sensitizer by the TiO2 surface is almost complete, reflecting the high degree of association between the TiO2 and the dye, fast charge injection and good electronic coupling between the sensitizer and the semiconductor. Nanosecond transient absorption spectra of the free sensitizer and of TiO2 surface bound sensitizer are recorded and compared. While the free
