As the field of theranostics expands, an imminent need arises for multifaceted polymer‐based nanotechnologies for clinical application. In this work, reversible addition‐fragmentation chain transfer (RAFT) aqueous emulsion polymerization is used to form 19F‐containing amphiphilic hybrid block copolymers (HBCs). Employing a cationic dendritic macromolecular chain transfer agent (mCTA), polymer frameworks comprised of chemically distinctive blocks of differing architectures (i.e., dendritic and grafted/linear) are strategically designed and synthesized. In aqueous media, self‐assembled polymer nanoparticles (PNPs) are formed. Their physicochemical properties and their potential as biomaterials for MRI applications are assessed. By showcasing a newly established mCTA and using these resulting PNPs as imaging probes, the work expands the design space of RAFT polymerization in biomedical research, paving the way for the development of more effective and versatile MRI imaging tools.

In recent years, the fully oxygen‐tolerant reversible addition‐fragmentation chain transfer (RAFT) polymerization has been emerging as a versatile and powerful tool for preparing well‐defined polymers. In this contribution, the symmetrical diethyl xanthogen disulfide (XD) is successfully used as an initiator, chain transfer agent, and termination (iniferter) agent to directly regulate the open‐to‐air RAFT polymerization. The high end‐group fidelity of polymer demonstrated by nuclear magnetic resonance (1H‐NMR) and matrix‐assisted laser desorption/ionization time‐of‐flight mass spectra indicates that sulfur‐centered xanthate radical can initiate and regulate RAFT polymerization of methacrylate (MA) under open conditions. It is believed that sulfur‐centered xanthate radical initiation strategy provides a powerful and minimalist tool for fully oxygen‐tolerant RDRPs.
