Understanding the self-assembly behavior of surfactants, including surface-active ionic liquids (SAILs) in deep eutectic solvents (DESs), holds significant value for both scientific research and practical applications. The properties of micelles are contingent upon a precise balance between hydrophobic and electrostatic interactions, as well as the steric factor that influences molecular clustering into self-organized structures. The strong H-bonding and elevated polarity of DESs influence the solubility and aggregation of surfactants and SAILs in DESs. Surfactants in DESs exhibit distinct self-assembly behavior compared to water, organic solvents, and ionic liquids (ILs), owing to their unique characteristics, robust H-bonding, and tunable properties. The interactions between surfactants and a DES are influenced by a range of complex factors, including the composition of the DES, its concentration, the type of hydrogen bond donor (HBD), the type of surfactant, the presence of water, and temperature. Furthermore, the solvophobic effect plays a crucial role in the self-assembly of surfactants in DESs, while intermolecular H-bonding interactions enhance this process. The self-assembly of surfactants in DESs represents an emerging area of study with significant potential for various applications, leveraging the customizable nature of these solvents.

摘要

Understanding the self-assembly behavior of surfactants, including surface-active ionic liquids (SAILs) in deep eutectic solvents (DESs), holds significant value for both scientific research and practical applications. The properties of micelles are contingent upon a precise balance between hydrophobic and electrostatic interactions, as well as the steric factor that influences molecular clustering into self-organized structures. The strong H-bonding and elevated polarity of DESs influence the solubility and aggregation of surfactants and SAILs in DESs. Surfactants in DESs exhibit distinct self-assembly behavior compared to water, organic solvents, and ionic liquids (ILs), owing to their unique characteristics, robust H-bonding, and tunable properties. The interactions between surfactants and a DES are influenced by a range of complex factors, including the composition of the DES, its concentration, the type of hydrogen bond donor (HBD), the type of surfactant, the presence of water, and temperature. Furthermore, the solvophobic effect plays a crucial role in the self-assembly of surfactants in DESs, while intermolecular H-bonding interactions enhance this process. The self-assembly of surfactants in DESs represents an emerging area of study with significant potential for various applications, leveraging the customizable nature of these solvents.
