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.
