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.
