Relationships between electron transport and redox center concentrations within molecular networks

A microscopic model was developed to describe electron diffusion among redox centers in a rigid network. The model describes electron diffusion coefficients, $D\sb E$, that are based on a random walk, and includes a hard-sphere approximation for the redox molecules, the electronic structure of redox centers, and intervening matrix effects. In dilute systems, $D\sb E$ rises sharply with redox center concentration, $C$; however at large C's, the hard sphere $D\sb E$ reaches a limiting value due to packing. Hard-sphere $D\sb E$ values for metalloprotein kinetics and a redox molecular diameter of 13 A (corresponding to Ru(bpy)$\sb3\sp{2+}$) are 1.9 $\times$ 10$\sp{-10}$ cm$\sp2$s$\sp{-1}$ and 5.0 $\times$ 10$\sp{-9}$ at 0.10 $M$ and 1.07 $M$, respectively.
