The combination of rigid and flexible segments of the rod-coil molecule, along with its unique morphology, opens up a wide range of possibilities for tailoring material properties, leading to applications in electro-optics, catalysis, nanotechnology, and biomedicine. Rod-coil molecules offer many benefits but suffer from complex synthesis and low yields. Polymerization-induced self-assembly (PISA) can be a promising approach for the synthesis of rod-coil molecules, as it does not require a catalyst, generates fewer side products, and allows the target morphology to be obtained at high concentrations. Here we perform e-beam-induced PISA by introducing an e-beam as an energy source to generate radicals in the solution. We confirm that the structure of the assemblies could be controlled by the dose rate and irradiation time and that they had colloidal stability. This approach provides uniform aggregates with precise size and shape, enhancing understanding of their behavior in liquids.
