Multicompartment polymer nanoparticles, such as two-faced Janus and patchy particles with distinct chemical domains, have attracted growing attention due to their unique interfacial and self-assembly behaviors arising from their asymmetric structures. In this review, we focus on nanoparticles with sizes in the tens of nanometers, synthesized via controlled polymerization techniques that allow scalable production with precise control over molecular characteristics. Specifically, we highlight miktoarm core cross-linked star polymers and Janus core–shell bottlebrush polymers as representative 0D and 1D anisotropic nano-objects featuring discrete cores and compartmentalized shells. We describe how controlled polymerizations can be used to covalently construct these complex architectures with spatial precision, enabling intramolecular phase segregation. Finally, we discuss their interfacial and self-assembling properties, as reported in both experimental studies and simulations.
