Semiconductor TiO2-colloids are stabilized by β-cyclodextrin (β-CD). Photoinduced electron transfer at the semiconductor (S.C.) solution interface is controlled in the S.C.-receptor assembly TiO2-β-CD. Trapping of TiO2-β-CD photoexcited conduction-band electrons by N,N'-dioctyl-4,4'-bipyridinium, C8 V2+, is 4.4 fold more effective than by N,N'-dimethyl-4,4'-bipyridinium. The kinetics of C8 V2+ reduction, inhibition experiments and laser flash photolysis studies reveal that the effective trapping of conduction-band electrons by C8 V2+ originates from its association to the β-CD receptor. Electron transfer from dye, proflavine, Pfl, to the S.C., is similarly controlled by the S.C.-receptor assembly. In the presence of the Pt modified semiconductor-receptor colloid, Pt-TiO2-β-CD, effective photoinduced H2-evolution occurs using Pfl as photosensitizer. Inhibition experiments and flow-dialysis measurements indicate that the effective H2-evolution originates from the association of Pfl to the β-CD receptor sites.
