Abstract
We demonstrate ultrafast symmetry-breaking charge separation (τCS <110 fs) in thin films of J-aggregated perylenediimide (PDI) multimers in a nonpolar polymethyl methacrylate polymer matrix (ε = 2.80–3.20). Theoretical calculations reveal the role of through-space electronic communication and π–π interactions promoting ultrafast charge separation in PDI multimers in the solid-state.
