CdSe nanoparticles stabilized with the amphiphilic diblock copolymer polystyrene‐ block ‐poly(4‐vinylpyridine) were spread from toluene dispersion on the water surface. Monolayers could be transferred onto solid substrates using the Langmuir‐Blodgett technique. By means of atomic force and scanning electron microscopy highly symmetric ring and disk‐like structures with diameters ranging between 150 nm and 1200 nm were observed.AFM image of a mixed monolayer of copolymer 12 and CdSe nanoparticles stabilized with polystyrene‐ block ‐poly(4‐vinylpyridine).
