Significance Time-dependent network analysis is used to describe the structural dynamics underpinning electron transport in disordered aggregates of molecular materials, advancing understanding of how charges move through noncrystalline aggregates. Specifically, our methodology allows for the characterization of how collective, dynamic fluctuations in the 3N nuclear degrees of freedom of the disordered multimolecule aggregate impact the statistically averaged charge motion through that aggregate. Our results describe the characteristic timescales over which electron hopping competes with nuclear reorganization, providing insight into the fundamental timescales governing charge transport in disordered systems.
