Polymer particles with submicrometer dimensions show promising applications in “bottom‐to‐top approach” to fabrication of materials with periodic structure, function, and composition. A novel approach to producing such materials is proposed, which employs core‐shell particles with specific structures and compositions. We report on the synthesis of core‐shell particles using interfacial polymerization and heterocoagulation techniques. The compositions of core‐forming material and/or the shell‐forming polymers were selectively controlled to be make the cores or the shells rigid or fluid, fluorescent or non‐fluorescent, organic or inorganic. Several potential applications of nanocomposite materials obtained from these particles are demonstrated, including three‐dimensional optical data storage and optical limiting and switching.
