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

Abstract

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.
