      abstract     = {This work focuses on the synthesis and self-assembly of
                      triphilic poly(2-oxazoline) triblock copolymers with high
                      fluorine content toward our future aim of developing
                      poly(2-oxazoline) magnetic resonance imaging (MRI) contrast
                      agents. A highly fluorinated 2-substituted-2-oxazoline
                      monomer, namely 2-(1H,1H,2H,2H-perfluorooctyl)-2-oxazoline,
                      was synthesized using the Grignard reaction. The
                      polymerization kinetics of the synthesized monomer was
                      studied, and it was used for the preparation of triblock
                      copolymers with hydrophilic 2-methyl-2-oxazoline,
                      hydrophobic 2-octyl-2-oxazoline, and fluorophilic blocks by
                      cationic ring-opening polymerization yielding polymers with
                      low relatively dispersity (1.2–1.4). The presence of the
                      blocks with the different nature in one copolymer structure
                      facilitated self-assembly of the copolymers in water and
                      dimethyl sulfoxide as observed by dynamic light scattering,
                      cryo-transmission electron microscopy, and small-angle
                      neutron scattering. The nanoparticle morphology is strongly
                      influenced by the order and length of each block and the
                      nature of solvent, leading to nanoparticles with
                      core–shell structure as confirmed by small-angle neutron
                      scattering. The reported poly(2-oxazoline) block copolymers
                      with high fluorine content have high potential for future
                      development of MRI contrast agents.},
