Method for manufacturing polymer nano particle

Abstract

The present invention relates to a method of manufacturing polymer nano particle having two-photon absorption compound at its central portion. The method of manufacturing polymer nano particle comprises the steps of dispersing a monomer for forming polymer nano particle and two-photon absorption compound into a solvent; supplying a given gas while stirring the solvent in which the monomer and the two-photon absorption compound are dispersed at a given temperature, in order to remove the dissolved oxygen contained in the solvent; supplying polymerization initiators into the solvent while stirring the solvent in which the monomer and the two-photon absorption compound are dispersed at a given temperature; and polymerizing the monomer for a given period of time while stirring the solvent in which the monomer and the two-photon absorption compound are dispersed at a given temperature.
