A fluorescent polystyrene microsphere with a diameter of 20 nm whose surface is modified with carboxylic acid groups was arranged selectively on one component of a diblock copolymer film of polystyrene and poly(4-vinylpyridine) (P4VP). Atomic force microscopy (AFM) observations showed that the microsphere was adsorbed only to the island part corresponding to the P4VP phase of the microphase structure of the film due to hydrogen bonding between the carboxylic acid groups of the microsphere and the pyridyl groups of P4VP. When the diameter of the microsphere was 50 nm, the microsphere was rarely adsorbed to the block copolymer film.
