Spontaneous transformation from micelles to vesicles associated with sequential conversions of comprising amphiphiles within assemblies.
نویسندگان
چکیده
A morphological transformation from hybrid micelles to giant vesicles was observed in aqueous dispersion associated with formation of a double-chained amphiphile as a result of the migration of dodecylamine from the amphiphilic imine to the amphiphilic aldehyde within the hydrophobic environment of amphiphilic aggregates.

Spotted vesicles, striped micelles, and responsive Janus assemblies induced by ligand binding
Selective binding of multivalent ligands within a mixture of polyvalent amphiphiles provides, in principle, a simple mechanism for driving domain formation in self-assemblies. Divalent cations are shown here to crossbridge polyanionic amphiphiles, which thereby demix from neutral amphiphiles and form spots or rafts within vesicles as well as stripes within cylindrical micelles. Calcium- and cop...

متن کاملRegulated assemblies and anion responsive vesicles based on 1,3-alternate oxacalix[2]arene[2]triazene amphiphiles.
Regulated assemblies from vesicles to micelles based on 1,3-alternate oxacalix[2]arene[2]triazine amphiphilic molecules were reported. The vesicular entities were responsive to anions and followed the selectivity in the order NO3(-) > Cl(-) > Br(-) > ClO4(-), driven by cooperative anion-π interactions and hydrogen bonding.
متن کاملGemini supra-amphiphiles with finely-controlled self-assemblies.
Novel gemini supra-amphiphiles, [Mim-4-Mim][DBS](2) and [Mim-4-Mim][DS](2), were facilely constructed. A slight variation of building blocks can effectively modulate the driving forces for the fabrication of gemini supra-amphiphiles, thus leading to the fine control of subsequent self-assemblies. [Mim-4-Mim][DS](2), constructed via electrostatic attraction, tends to form micelles and hexagonal ...
متن کاملVisualizing worm micelle dynamics and phase transitions of a charged diblock copolymer in water.
Assemblies of block copolymer amphiphiles are sometimes viewed as glassy, frozen, or static colloids, especially in strongly segregating solutions. Here, we visualize by fluorescence microscopy and AFM the dynamics and transitions of single cylindrical micelles and vesicles composed of a charged diblock copolymer in water. In mapping the salt- and pH-dependent phase diagrams of a near-symmetric...
