Self-Organization in Solutions of Stiff-Chain Amphiphilic Macromolecules

Abstract: Conformational properties of amphiphilic stiff-chain macromolecules in concentrated solutions in poor solvent have been studied via computer modeling. We have found that the conformational state of macromolecules in such systems depends on the macromolecular stiffness and on the way the solution has been prepared. Thus, if the concentration of globules increased from a very diluted solution, the globules remain stable, independent of the macromolecular stiffness, and do not aggregate even in concentrated solut… Show more

“…Similarly, when referring to the formation of unimolecular micelles from the self-assembly of polymers exhibiting an amphiphilic character, it is the type of hydrophobes, hydrophobe sequence distribution and grafting density, polymer concentration, chain stiffness, and hydrophilic-to-hydrophobic ratio that will determine the intra- vs intermolecular balance. For their structural similarity to proteins, the formation of unimolecular micelles has largely been examined for random copolymers of monomers bearing short hydrophilic and hydrophobic moieties. ,, The advancement of polymerization methods enabling the synthesis of complex macromolecular architectures has also allowed for the study of intrachain association of polymers with more complex architectures including those with long or multicomponent branches. …”

“…[30][31][32][33][34][35] The globules of such macromolecules have a complex core-shell structure: the interiors consist of hydrophobic units, while the outer shell is composed of hydrophilic units. In semidilute solution, the amphiphilic flexible macromolecules condense into individual soluble globules 31 while the rigid macromolecules tend to aggregate with formation of braid fibril-like complexes 36 or bundle aggregates of a few chains. 37 In both cases, the hydrophobic backbones of the chains intertwine and form a core, whereas hydrophilic groups are located on the surface.…”
