Aggregation of p-Sulfonatocalixarene-Based Amphiphiles and Supra-Amphiphiles

Aggregation of p-Sulfonatocalixarene-Based Amphiphiles and Supra-Amphiphiles

p-Sulfonatocalixarenes are a special class of water soluble macrocyclic molecules made of 4-hydroxybenzenesulfonate units linked by methylene bridges. One of the main features of these compounds relies on their ability to form inclusion complexes with cationic and neutral species. This feature, together with their water solubility and apparent biological compatibility, had enabled them to emerg...

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

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.

Gemini 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 ...

Aggregation of Amphiphiles in Ternary Mixtures

We present an improved version of an earlier Larson-type model of amphiphiles. Detailed descriptions of the algorithms are given and some situations where care must be taken are pointed out We use the model to calculate the condensation transition temperature of amphiphiles in a ternary mixture. The concentration percolation threshold and percolation critical exponent of arnphiphile clusters at...
