Polymer-Derived Janus Particles at Multiple Length Scales

Polymer-derived Janus particles, both polymeric and composites of organic and inorganic components, hold promise as key elements in future applications due to their unique morphologies and functionalities. In this Perspective, recent progress in the synthesis and generation of polymer-derived Janus particles at the single-chain, nanoscopic, and macroscopic length scales is described. We focus on significant achievements in the control of distinct compartmentalization and large-scale synthesis of Janus nanoparticles, both of which are crucial for their practical use. The challenges and opportunities associated with polymer-derived Janus particles are outlined to inspire the development of new strategies for the large-scale synthesis of Janus particles with integrated functionalities.
