Key Points

Ultrafast charge separation occurs in thin films of J-aggregated perylenediimide, revealing remarkable speed.
Theoretical calculations support the findings of charge separation in a nonpolar polymer matrix.
A lower dielectric constant of the medium (ε = 2.80-3.20) plays a crucial role in the charge dynamics.
Understanding these ultrafast processes may aid in developing advanced materials for electronic applications.

Implication

Demonstrates ultrafast charge separation (τ CS < 110 fs) in thin films, indicating unique properties of J-aggregated PDI multimers.

Abstract

We demonstrate ultrafast symmetry-breaking charge separation ( τ CS <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...
