1 Results Self-assembling of monodisperse polymeric nanoparticles is a perspective method of obtaining photonic crystalline materials for optoelectronics,telecommunication industry and optosensorics.For tuning optical characteristics of photonic crystals it is advisable to functionalize nanoparticles by dyes absorbing or emitting light in the vicinity of the photonic band gap,which position depends on the nanoparticle diameter.To prepare monodisperse nanoparticles with the dye-functionalyzed surface emulsion copolymerization of styrene with functional comonomers methacrylic acid[1] or N-vinylformamide was investigated.Dyes were attached onto the surface of nanoparticles either by covalent binding with surface amino groups of poly(styrene-co-N-vinylformamide-co-4-aminostyrene) particles[2] or by the ionic interaction of cationic dyes (Rhodamine 6G,Acriflavine,and 1-(3-ammonium-propyl)-4-[(E)-2-(3,4-dimethoxyphenyl)-1-ethenyl]pyridinium perchlorate) with surface carboxylic groups of poly(styrene-co-methacrylic acid) particles.
