Effect of structural fluctuations on charge carrier mobility in small molecules

What is it about?

The effect of structural fluctuations on charge transport was studied through the polaron hopping model. Theoretical results show that for the studied oligomers, the charge transfer kinetics follows the static non-Condon effect and the charge transfer decay at particular site is exponential, non-dispersive and the rate coefficient is time independent.

Why is it important?

The stochastic study by Monte-Carlo simulation clearly shows that the effect of dynamic fluctuations on charge transport in π-stacked molecules follows the static non-Condon principle which facilitates the non-dispersive charge transfer kinetics.

Charge transport properties are strongly depends on the typical disorder, whether static or dynamic disorder.
