Invertible Amphiphilic Homopolymers

Journal of the American Chemical Society, 2004
Stimuli-responsive polymers and assemblies are viable candidates for the so-called "smart" materials. In this communication, we report a new class of amphiphilic homopolymers that forms micelle-like structures in polar solvents and inverted micelle-like structures in apolar solvents.

Amphiphilic Building Blocks for Self-Assembly: From Amphiphiles to Supra-amphiphiles

Accounts of Chemical Research, 2012
The process of self-assembly spontaneously creates well-defined structures from various chemical building blocks. Self-assembly can include different levels of complexity: it can be as simple as the dimerization of two small building blocks driven by hydrogen bonding or as complicated as a cell membrane, a remarkable supramolecular architecture created

Amphiphilic cyclodextrin nanoparticles

International Journal of Pharmaceutics, 2017
Cyclodextrins are cyclic oligosaccharides obtained by enzymatic digestion of starch. The α-, β- and γ- cyclodextrins contain respectively 6, 7 and 8 glucopyranose units, with primary and secondary hydroxyl groups located on the narrow and wider rims of a truncated cone shape structure.

Amphiphilic Bistable Rotaxanes

Chemistry – A European Journal, 2003
AbstractTwo molecular shuttles/switches—a slow one and a fast one—in the shape of amphiphilic, bistable [2]rotaxanes have been synthesized and characterized. Both [2]rotaxanes contain a hydrophobic, tetraarylmethane and a hydrophilic, dendritic stopper.

Hexayne Amphiphiles and Bolaamphiphiles

Chemistry – A European Journal, 2020
AbstractOligoynes with two or more conjugated carbon–carbon triple bonds are useful precursors for carbon‐rich nanomaterials. However, their range of applications has so far been severely limited by the challenging syntheses, particularly in the case of oligoynes with functional groups.

Amphiphilic, Regioregular Polythiophenes

Macromolecules, 2002
The synthesis, characterization, and solid-state morphology of regioregular, amphiphilic polythiophenes based on 3-dodecyl-3'-(3,6,9,12-tetraoxatridecanyl)-2',5-bithiophene are described. These polythiophenes form stable monolayers on the water subphase of a Langmuir trough and are transferable (Langmuir-Blodgett deposition) to solid substrates to give

Amphiphillic Organic Crystals

Journal of the American Chemical Society, 2009
The amphiphillic character, that is, the capacity to simultaneously attract and repel water, has been traditionally reserved to organic molecules such as phospholipids and surfactants, containing both hydrophilic and hydrophobic groups within the same molecule.

Lipase Polystyrene Giant Amphiphiles

Journal of the American Chemical Society, 2002
A new type of giant amphiphilic molecule has been synthesized by covalently connecting a lipase enzyme headgroup to a maleimide-functionalized polystyrene tail (40 repeat units). The resulting biohybrid forms catalytic micellar rods in water.

Evolution of Supra-Amphiphiles from Amphiphiles

2017
Molecular amphiphiles are molecules that carry both a hydrophilic part and a hydrophobic part, linked by covalent bonds. In contrast with molecular amphiphiles, supramolecular amphiphiles (or supra-amphiphiles) are amphiphiles that are formed on the basis of noncovalent interactions.
