Polyelectrolyte-multivalent molecule complexes: physicochemical properties and applications

Abstract

The complexation of polyelectrolytes with other oppositely charged structures gives rise to a great variety of functional materials with potential applications in a wide spectrum of technological fields. Depending on...

Molecular-level insights into a tripolyphosphate and pyrophosphate templated membrane assembly

“…The modulation of the aggregation behavior of ionic amphiphiles in the presence of polyelectrolytes (polycations or polyanions) was widely documented in the literature. [63][64][65] The critical aggregation concentration of the amphiphiles is generally reduced in the presence of polyelectrolytes. 64,66 Although TPP or PPi may not be regarded as polyelectrolytes, the templating effect through multiple charge-charge interactions has similarities with the polyelectrolyte-like effect.…”

Phase Behavior and Electrochemical Properties of Highly Asymmetric Redox Coacervates

“…Over the past century, there has been extensive research on the phase separation of oppositely charged macromolecules due to weak interactions. − This field witnessed significant breakthroughs in the 1930s with the work of de Jong and Kruyt who published a series of articles describing what we know today as complex coacervates. , According to Alexander Oparin’s origin of life theory, complex coacervates are defined as solutions of highly concentrated polyelectrolyte complexes that are dispersed in a continuous phase made mostly by water molecules. As coacervates are liquid in nature, they could act as membraneless compartments capable of loading and releasing metabolites, promoting specific chemical reactions, and dynamically modifying their structure without dissolving .…”

“…In recent years, it was shown that polyelectrolytes can undergo coacervation not only by interacting with other polyelectrolytes but also by interacting with low-molecular-weight multicharged ions (multivalent ions). , This class of polyelectrolyte/multivalent-ion complexes and traditional polycation/polyanion coacervates has historically evolved as different research fields. − However, polyelectrolyte/multivalent-ion complexes can be thought of as a particular case of coacervates, where one of the polyelectrolytes has been replaced by a “short-chain” polyion. While symmetric complex coacervates ( i.e.…”

The effect of monomer polarizability on the stability and salt partitioning in model coacervates

“…Coacervation is also a type Liquid Liquid Phase Separation (LLPS) where the emergent polymerrich phase still maintains its liquid-like properties. 1,2 Despite the large body of research regarding the properties of the condensates created through LLPS, [3][4][5] the exact mechanism leading to their formation has yet to be fully understood. However, experimental results of the phase separation of synthetic polymers and disordered proteins have suggested that electrostatic, dipole, and hydrophobic interactions play an important role in this process.…”
