Complex pH-Dependent Interactions between Weak Polyelectrolyte Block Copolymer Micelles and Molecular Fluorophores

Abstract: Amphiphilic block copolymers with weak polyelectrolyte blocks can assemble stimulus-responsive nanostructures and interfaces. Applications of these materials in drug delivery, biomimetics, and sensing largely rely on the well-understood swelling of polyelectrolyte chains upon deprotonation, often induced by changes in pH or ionic strength. This deprotonation can also tune interfacial interactions between the polyelectrolyte blocks and surrounding solution, an effect which is less studied than morphological swe… Show more

“…Amphiphilic polymers, bearing both hydrophobic and hydrophilic molecular components, show unique and specific properties and are quite different from those of homopolymers. Recently, the structures and behaviors of self-assembled amphiphilic polymers have been revealed in detail. , Information related to the macromolecular assembly will provide useful strategies for the design and structural control of the molecular level targeting of functional materials. Amphiphilic polymers have attracted considerable attention as surfactants due to the coexistence of opposing properties (hydrophobic and hydrophilic) in a single molecule. They enable hydrophobic particles such as carbon nanotubes, metal particles, dyes, or pigments to be efficiently dispersed in aqueous media.…”
