The Hierarchical Self-Assembly of Charge Nanocarriers: A Highly Cooperative Process Promoted by Visible Light


  • We wish to thank the CNRS, the icFRC, and the University of Strasbourg for financial support. This work was supported by a doctoral fellowship of the French Ministry of Research (F.N.). We acknowledge the ESF-COST action on Systems Chemistry. We are also grateful to E. Aweke, S. Coulibaly, M. Bernard, and J. Raya for help at various stages.

Let there be more light: Triarylamine-based building blocks respond to visible-light exposure by the formation of cationic radicals that hierarchically self-assemble into molecular wires, which in turn combine within larger fibers (see picture). The stimuli-responsive supramolecular scaffold, which is created by charge transfer and reversibly broken up by heating, prevents the quenching of holes within the wires.
