Electron tunneling in micelles and vesicles

Other interesting examples of the organized molecular structures used to increase the quantum yield of charge photoseparation are micelles and vesicles. Micelles represent aggregates of surfactant molecules, one end of which is hydrophobic and the other hydrophilic. On reaching a certain critical concentration in a solution, these molecules group into spherical formations in which either the hydrophilic ends of the molecules are turned towards the micelle centre while their hydrophobic ends form its surface or vice versa. Micelles of the former type are usually formed in non-polar solvents and those of the latter type in polar solvents. The micelle is schematically represented in Fig. 1(d).

The mechanism of PET in membranes including those based on electron tunneling are discussed in more detail in Chapter 159 by K. I. Zamaraev, V. N. Parmon, S. V. Lymar.
