Photoinduced electron transfer in the head group region of sodium dodecyl sulfate micelles

Photoinduced electron transfer between octadecylrhodamine B (a hole donor) and N, N-dimethyl-1-napthylamine (hole acceptor), located in the head group region of sodium dodecylsulfonate micelles, has been examined for different acceptor concentrations using time resolved fluorescence. The experimenta...

Description
Summary:Photoinduced electron transfer between octadecylrhodamine B (a hole donor) and N, N-dimethyl-1-napthylamine (hole acceptor), located in the head group region of sodium dodecylsulfonate micelles, has been examined for different acceptor concentrations using time resolved fluorescence. The experimental results were analyzed using the Marcus distance-dependent transfer rate modified to take into account the heterogeneous nature of the micelles. Diffusion of the donor/acceptors is included in the theoretical analysis. The results are compared with earlier experiments involving the same donor–acceptor combination but in a different type of micelle.
