This review summarizes recent work in the field of polyelectrolyte stars and cylindrical brushes. Synthesis of anionic and cationic polyelectrolyte stars and cylindrical brushes by different synthetic strategies is introduced. Solution properties such as titration, osmotic pressure, and inter-polyelectrolyte complexes (IPECs) of the stars and brushes are briefly discussed. We also highlight the use of core-shell polyelectrolyte brushes as the template for the preparation of superparamagnetic hybrid cylinders.

“…The uptake of iron ions into the polymer core was confirmed by various characterization techniques including Fourier-transform infrared (FTIR) spectroscopy, [38] UV-vis spectroscopy, and SFM and transmission electron microscopy (TEM), [38] besides the apparent color change before and after the iron ion uptake.…”

“…The polychelate of Brush 1 and Fe 3+ ion has an absorption edge of about 425 nm, with a distinct shoulder at around 350 nm, which corresponds to the broad absorption peak of FeCl 3 at this position. Since the pure polymer brush has almost no absorption in the observation wavelength range, [38] the absorbance of the polychelate can be attributed exclusively to the coordinated Fe 3+ ions. After the formation of magnetic nanoparticles, the absorption shoulder at 350 nm almost disappears.…”

Well‐defined cylindrical polymer brushes with poly(acrylic acid) (PAA) cores and poly(n‐butyl acrylate) (PnBA) shells have been synthesized via a combination of anionic polymerization and atom transfer radical polymerization. These amphiphilic brushes are unimolecular cylindrical micelles and can be used as single‐molecular templates for the synthesis of inorganic nanoparticles, because the carboxylic acid groups (or carboxylate groups, after neutralization) in the polymer core can coordinate with various metal ions such as Fe3+ and Fe2+. Ultrafine magnetic nanoparticles were successfully synthesized within the core of these polymer brushes, as confirmed by various characterization techniques. Mössbauer spectroscopy and magnetization measurements indicate that the hybrid nanocylinders exhibit interesting superparamagnetic behavior.

“…Therefore, polymer brushes show promise in the field of intramolecular nanoengineer ing as, for example, nanocontainers for inorganic nanoparticles or nanofibers [15][16][17] and polymeric carriers for targeted drug delivery [18]. Nanocompos ite materials obtainable via this technology are appli cable in opto , acousto , and spin electronics in information storage devices and actuators [19,20] as well as for the development of materials with new properties, e.g., ultrasoft elastomers [21,22].…”

Methods for the synthesis of polymer (molecular) brushes via various controlled radical poly merization approaches are considered, and their properties are analyzed. Special attention is paid to atom transfer radical polymerization, which is most frequently used for these purposes. The potential of the syn thesis of molecular brushes with various chemical structures, including amphiphilic brushes, is demonstrated in many examples.
