FREE: JSD Article of the Month "Constructing Surfactant Systems with the Characteristics of Gemini and Oligomeric Surfactants Through Noncovalent Interaction"

“Gemini surfactants have been researched for several decades, but they have never really been commercialized for industrial applications because they are difficult to synthesize and purify,” says Journal of Surfactants & Detergents Editor-in-Chief George Smith. In Smith’s JSD pick for March, the review “Constructing Surfactant Systems with the Characteristics of Gemini and Oligomeric Surfactants through Noncovalent Interaction,” Yilin Wang and colleagues from the Beijing National Laboratory for Molecular Sciences, in China, have shown that it is possible to construct gemini surfactants through noncovalent interactions, including hydrogen bonding, metal-ligand coordination and electrostatic attraction. The reversibility of the interactions through pH, light, salt and temperature allows for easy control of the gemini surfactant structure using commercially available monomer surfactants. The article will be available online, free of charge, until May 16, 2016.

Abstract


The superior physicochemical properties of gemini and oligomeric surfactants look promising in a variety of different applications. However, tedious covalent synthesis and complicated purification limit the development of these novel surfactants. Recently, it has been demonstrated as feasible to use noncovalent interactions to construct surfactant systems with the characteristics of gemini or oligomeric surfactants. This short review discusses the strategies of constructing gemini-like or oligomeric-like surfactants through noncovalent interactions by choosing proper building blocks, single-chain surfactants and gemini surfactants along with connecting molecules containing double or multiple binding sites. The current progress in this field has been summarized. This very simple and efficient way to obtain gemini and oligomeric surfactants may make a practical impact on the surfactant industry.
