It is challenging to increase the rigidity of a macromol. while maintaining solubility Established strategies rely on templating by dendrons, or by encapsulation in macrocycles, and exploit supramol. arrangements with limited robustness. Covalently bonded structures have entailed intramol. coupling of units to resemble the structure of an alternating tread ladder with rungs composed of a covalent bond. We introduce a versatile concept of rigidification in which two rigid-rod polymer chains are repeatedly covalently associated along their contour by stiff mol. connectors. This approach yields almost perfect ladder structures with two well-defined π-conjugated rails and discretely spaced nanoscale rungs, easily visualized by scanning tunnelling microscopy. The enhancement of mol. rigidity is confirmed by the fluorescence depolarization dynamics and complemented by mol.-dynamics simulations. The covalent templating of the rods leads to self-rigidification that gives rise to intramol. electronic coupling, enhancing excitonic coherence. The mols. are characterized by unprecedented excitonic mobility, giving rise to excitonic interactions on length scales exceeding 100 nm. Such interactions lead to deterministic single-photon emission from these giant rigid macromols., with potential implications for energy conversion in optoelectronic devices.
