Abstract

Abstract : 1D helical nanowires from "supramolecular low‐bandgap polymers" facilitate the formation of photocharges induced with a low‐power white‐light source. The photocharges in this nanoscopic confinement exhibit extraordinarily long lifetimes in the order of many hours, which gives rise to delocalized and mobile charges at high concentrations close to the metal insulator threshold. These systems show macroscopic photoconductivity and charge transport properties similar to strongly doped organic semiconductors, and thus provide valuable insight into the structure–property relationship in organic electronic materials.
