Supra-amphiphiles formed by complexation of azulene-based amphiphiles and pyrene in aqueous solution: from cylindrical micelles to disklike nanosheets.

چکیده
We have fabricated supra-amphiphiles by charge-transfer complexation of azulene-based amphiphiles and pyrene in water, and the self-assembled nanostructures can reversibly change between cylindrical micelles and disklike nanosheets in response to interaction with guest molecules.

Water-supported organized structures based on wedge-shaped amphiphilic derivatives of dipyrrolyldiketone boron complexes.
Wedge-shaped amphiphilic derivatives of 1,3-dipyrrolyl-1,3-propanedione boron complexes, with one or no aliphatic chains attached at one aryl moiety and three hydrophilic chains at the other, exhibited formation of assembled structures in aqueous solutions. UV/vis, fluorescence and DLS analyses suggested that the wedge-shaped amphiphiles exist in assembled modes in the solution state, and TEM m...
متن کاملMolecular Packing in Cylindrical Micelles
The elongated shape of linear, worm-like, micelles is among the most common aggregation geometries of amphiphilic molecules in aqueous solutions. The cylindrical body of these uni-dimensional micelles can be regarded as an intermediate packing geometry, of a higher growth dimensionality than that of a spherical micelle and lower than that of a planar bilayer. In all these three canonical struct...
متن کاملControlled self-assembly of carbohydrate conjugate rod-coil amphiphiles for supramolecular multivalent ligands.
Carbohydrate conjugate rod-coil amphiphiles were synthesized and their self-assembling behavior in aqueous solution was investigated. These amphiphiles were observed to self-assemble into supramolecular structures that differ significantly depending on the molecular architecture. The rod-coil amphiphiles based on a short coil (1) self-assemble into a vesicular structure, while the amphiphiles w...
متن کاملLow Molecular Weight Micelles
I.F. Uchegbu et al. (eds.), Fundamentals of Pharmaceutical Nanoscience, DOI 10.1007/978-1-4614-9164-4_2, © Springer Science+Business Media New York 2013 Abstract Low molecular weight amphiphile micelles are formed from the selfassembly of comparatively hydrophilic amphiphiles (molecular weight <1,500 Da). These structures may be spherical or present as nanofi bres in the case of peptide amphiph...
متن کاملThe role of spacers on the self-assembly of DNA aptamer-amphiphiles into micelles and nanotapes.
The self-assembly of single-stranded DNA (ssDNA) aptamer-amphiphiles was influenced by the choice of spacer used to link the hydrophobic tail and aptamer headgroup. Aptamer-amphiphiles without spacers or with hydrophilic spacers formed globular micelles while amphiphiles with hydrophobic spacers formed bilayer nanotapes, which are the first such structures formed by DNA-amphiphiles.
