Single‐molecule semiconductor nanomaterials with π‐stacked structures in solution and the solid state are prepared from a polystyrene backbone and densely tethered π‐conjugated polyquinoline side chains (see figure). Highly structured optical absorption spectra and exclusive broad, structureless yellow excimer emission in toluene solutions confirm the π‐stacked structures and collective optical properties of the side‐chain conjugated polymers.
