Guazzelli, Elisa published the artcileSingle-chain folding and self-assembling of amphiphilic polyethyleneglycol-modified fluorinated styrene homopolymers in water solution, Name: 2,5,8,11-Tetraoxatridecan-13-ol, the main research area is amphiphilic polyethyleneglycol modified fluorinated styrene homopolymer self assembling.

Amphiphilic tetrafluorostyrene monomers (EFSn) carrying in the para position a polyethyleneglycol (PEG) chain with varied lengths (n = 3-13) were synthesized and polymerized by ARGET-ATRP to obtain the corresponding amphiphilic homopolymers pEFSn-x with controlled and tailored polymerization degrees (x = 8-135). All polymers presented a reversible thermoresponsive LCST-type behavior, in water/methanol mixture when n ≤ 4 or in pure water when n ≥ 8, with a cloud point (Cp) temperature in the range 30-40°C strictly dependent on the length of the PEG side chain. Combined small angle X-scattering (SAXS) and dynamic light scattering (DLS) measurements were used to study the self-assembly behavior in water of the water-soluble amphiphilic homopolymers. SAXS confirmed the formation of compact-sized and spherical single-chain self-folded nanostructures below Cp, that generally presented small hydrodynamic diameters (Dh ≤ 11 nm) as proven by DLS anal. Above Cp, much larger multi-chain aggregates were formed (Dh ≥ 800 nm), that reversibly turned back to collapsed nanostructures on cooling below the Cp temperature By contrast, the polymers were not able to self-assemble in THF or DMF solutions, in which they adopted conventional random coil conformations.
