“…This increase by a factor of 16 is much smaller than the 133-fold increase in length as expected for diffusion-controlled reactions with long molecules. It shows the strong influence of “diffusive interaction (DI)”. ,,,, If pF 133 is regarded as 133 reactive sites spaced along a line, reaction of an electron with one of them removes that electron precluding reaction of that electron with any of the other sites. Data in Figure indicates that DI reduced the rate by a factor of 133/16 = 8.3.…”

“…Here, eq comprises the first two terms of a series that converges rapidly. While eq is known to have inherent failings at very short times and high concentrations, especially when combined with low diffusion constants, , it is the form recovered for electron transfer to small molecules ,, and for reactions of more extended objects ,, and was used in the first application to conjugated polymers . For large molecules, the form of the transient term in eq has been described as universal .…”

“…The actual shapes of the immobilized vesicles on glass are unknown, and it can be expected that they are not perfectly symmetric, so that the vesicle radius R ‘ as measured by our experiments is regarded as a mean size parameter of the vesicle. However the difference between a circular, a hemispherical, and even cylindrical object is small, and hence the corrections to the size parameter from the shape dependence are also expected to be relatively small within a reasonable range of shapes. The distributions clearly indicate the heterogeneity in the sizes of vesicles adsorbed on glass.…”
