We investigate synthetic strategies of cationic surface-charged nanoparticles using cyclopropenium-based (CP) monomers and block copolyelectrolytes (BCPEs) via surfactant-free emulsion polymerization. The monomers and BCPEs themselves were found to stabilize oil-in-water emulsions. With these systems, the hydrodynamic diameters of the resultant particles can be reliably tuned from 30 to 100 nm, simply by varying the amount of CP monomer added. As CP is a remarkably stable carbocation, the… Expand
