Studies On Sucralose-Based Low Molecular Weight Gelators, Malick Samateh

Dissertations and Theses

Amphiphiles are molecules with both hydrophilic head and hydrophobic tail groups. Examples of amphiphiles include surfactants, detergents, soaps, bile acids/salts and lipids. Due to their amphiphilic nature, they tend to self-assemble in solution via non-covalent interactions such as hydrogen-bonding, π-π stacking and donor–acceptor interactions to form hierarchical morphologies like micelles, lamellae and fibers. The ones capable of subsequently forming gels are known as low molecular weight gelators (LMWGs). LMWGs usually form “polymer-like” fibers that interact to form a three-dimentional network known as a Self-Assembled Fibrillar Network (SAFIN), which entraps and immobilizes the entire solvent pool to form a viscoeslatic material …
