“…It can be concluded that the [mim-C 4 -mim]Br 2 -(SDBS-0,11) 2 sample undergoes a spontaneous phase transition from micelles to vesicles with the increase of concentration. In recent years, the transition from micelles to vesicles triggered by pH, ionic strength, external additives, and oxidation was still an interesting phenomenon and widely studied by researchers. − …”

The construction of pseudogemini surfactants based on noncovalent interactions (such as electrostatic interaction and π−π stacking) was a powerful method to assemble well-defined aggregates in aqueous solution. The mixtures of butane-1,4bis(methylimidazolium bromide) ([mim-C 4 -mim]Br 2 ) and positional isomers of sodium dodecyl benzene sulfonate (SDBS-0,11 or SDBS-3,8) in a molar ratio of 1:2 were studied to characterize the effect of straight and branched alkyl chains on the aggregation behavior of pseudogemini surfactants. Spontaneous phase transition from micelles to vesicles was formed by these two kinds of complexes. Interestingly, a densely stacked onion-like structure (multilamellar vesicles) with more than one dozen layers was fabricated. The micelle and vesicle phases were characterized in detail by cryogenic transmission electron microscopy, polarized optical microscopy, dynamic light scattering, and rheological measurements. It can be clearly demonstrated that the structure of alkyl chain can significantly influence the surface adsorption, solution self-assembly, and aqueous two-phase system of pseudogemini surfactants. Our work provided a convenient technique to achieve controlled self-assembly by introducing positional isomers of surfactants.

“…A vesicle to micelle to vesicle transformation was reported by Sarkar et al , They showed such a transition in a mixture of a cationic surfactant and an anionic ionic liquid. A stand-out, biocompatible transformation of vesicles to micelles to vesicles using a cationic surfactant and cyclodextrin in an aqueous medium was shown by Ghosh et al Maity et al followed up their findings with the semicarbazide and thiosemicarbazide pyrene derivatives to look into the dynamics of the critical penetration of interfacial water into the periphery of reverse micelles . Looking to apply the reverse micellar interface to a new facet, Bhunia et al explored the dynamics of photoinduced electron transfer (PET) inside an aqueous pool of reverse micelles using copper nanoclusters (Cu NCs) (Figure ).…”

Chemical and biological interfaces are of various types, which could be between two materials of the same and/or different states, two phases of the same material, biological substrates and the outer environment, surfactant or polymeric membranes and the bulk, and so forth. Small-molecule guests frequently interact with such interfaces that decide their functionalities. The structural and behavioral properties undergo considerable characteristic changes, which control their final course of action in the targeted application. This Perspective will discuss mainly the chemical interfaces constituted by the surfactants, polymers, lipids, and nucleic acids and their impacts on the dynamics of small-molecule guests. Some specific and interesting phenomena and future prospects will be elucidated in this Perspective.

“…Stellated or hybrid supramolecular nanoparticles could be formed by orthogonal self-assembly driven by host–guest complexation, π–π stacking, iron-carboxylate coordination, and hydrogen bonds, which possessed superior antitumor performance and antimetastasis capability . Similarly, a series of worm-like micelles, monolayer vesicles (MVs), bilayer membranes, lamellas, rodlike structures, as well as the morphology evolutions from microtubes to vesicles, hollow spheres to rod-like particles, and vesicles to worm-like to vesicular multilamellas were developed successively by taking advantage of the host–guest molecular recognition. − …”

Supramolecular assembly has attracted significant attention and has been applied to various applications. Herein, a β−γ-CD dimer was synthesized to complex different guest molecules, including single-strand polyethylene glycol (PEG)modified C 60 (PEG-C 60 ), photothermal conversion reagent (IR780), and dexamethasone (Dexa), according to the complexation constant-dependent specific selectivity. Spherical or cylindrical nanoparticles, monolayer or bilayer vesicles, and bilayer fusion vesicles were discovered in succession if the concentration of PEG-C 60 was varied. Moreover, if near-infrared light was employed to irradiate these nanoassemblies, the thermo-induced morphological evolution, subsequent cargo release, photothermal effect, and singlet oxygen ( 1 O 2 ) generation were successfully achieved. The in vitro cell experiments confirmed that these nanoparticles possessed excellent biocompatibility in a normal environment and achieved superior cytotoxicity by light regulation. Such proposed strategies for the construction of multilevel structures with different morphologies can open a new window to obtain various host−guest functional materials and achieve further use for disease treatment.
