Synthesis of Novel Cross-Linked Fluorinated Cooligomeric Nanoparticles

Fluoroalkanoyl peroxides reacted with dimethacrylate monomer containing poly(oxyethylene) units and acrylic acid to afford cross-linked fluoroalkyl end-capped cooligomeric nanoparticles in excellent to moderate isolated yields under very mild conditions. These cross-linked fluorinated nanoparticles thus obtained were nanometer size-controlled, and these nanoparticles were found to exhibit a good dispersibility and stability in a variety of common organic solvents including water. Interestingly, these cross-linked fluorinated cooligomeric nanoparticles were applied to the preparation of colloidal stable cross-linked fluorinated cooligomeric magnetite nanoparticles.
