Noncovalent crosslinking between polyvinyl pyridine and a copolymer of acrylic acid led to the formation of a polymer nanoparticle. In the presence of a metastable-state photoacid, reversible dissolution and formation of the nanoparticle can be controlled by visible light. Photo-induced proton transfer from the photoacid to the polymers broke the hydrogen bonding and ionic bonding and led to the dissolution of the nanoparticle. Cycles of dissolution and formation were controlled by turning on and off irradiation, and were demonstrated by the transmittance change.
