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 the role of through-space electronic communication and π-π interactions promoting ultrafast charge separation in PDI multimers in the solid-state.

非极性固态环境下j聚集的苝酰亚胺多聚体薄膜的超快对称破缺电荷分离

我们证明了在非极性聚甲基丙烯酸甲酯聚合物基体（ε = 2.80-3.20）中，j聚集的苝酰亚胺（PDI）多聚体薄膜的超快速对称破断电荷分离（τCS <110 fs）。理论计算揭示了通过空间电子通信和π-π相互作用促进固态PDI多晶体中超快电荷分离的作用。
