Novel amphiphiles with preorganized functionalities—formation of Langmuir-films and efficiency in mineral flotation

Supramolecular Assemblies of a New Series of Gemini-Type Schiff Base Amphiphiles at the Air/Water Interface: In Situ Coordination, Interfacial Nanoarchitectures, and Spacer Effect

“…Furthermore, they have a series of parameters such as the length of hydrophobic chains, the size of hydrophilic headgroups, the type of counterions, and the flexibility and polarity of the spacer that can induce a richer diversity of aggregate morphologies. − As a result, the special molecular geometries of gemini amphiphiles could lead to interesting aggregate structures both in solution and at the air/water interface. However, compared with the extensive investigations in solution systems, there are a fewer reports on the interfacial assemblies of gemini amphiphiles. − Different from conventional amphiphiles, the spacer in gemini amphiphiles is expected to have a great influence on the interfacial properties and the wealth of morphologies in organized films. − Previously, our group has investigated the interactions between gemini amphiphiles and DNA and observed interesting properties and surface morphologies of gemini/DNA complex films . In addition, we have also designed a series of imidazole-based gemini amphiphiles and investigated their interfacial properties as well as the regulation of surface properties of the complex films of gemini/dye and gemini/polyoxometalate (POM) hybrid films …”

Equilibrium morphologies of nonionic lipid–nanoparticle mixtures in water: A self-consistent mean-field prediction

“…erties to improve the solubility of these hydrophobic molecules. Amphiphiles are used to encapsulate the otherwise nonsoluble materials and have found use, e.g., in a wide range of medical applications (for controlled drugs released) [11][12][13][14][15][16][17] and in the minerals industry where amphiphiles are common additives during flotation processes (as particle collectors) [18][19][20][21].…”

Synthesis, Langmuir and Langmuir–Blodgett film behaviour of new dendritic amphiphiles

“…a geometrically well-defined central building block composed of ethynylene substituted aromatic spacers, with different numbers of amphiphilic segment groups, which are also of rigid geometric design, was used. 7,8 Another topical concept of supramolecular chemistry, which is the strategy of multiple branching, has also been introduced into the design of new surfactant structures, yielding dendritic amphiphiles. 9 The multiple branching results in organic molecules with interesting properties and in highly stable non-crystalline supramolecular architectures.…”
