Supramolecular organogels formed by monochain derivatives of succinic acid
Abstract.
The monoalkyl chain derivatives of succinic acid self-assemble into ordered bilayer aggregates by forming
dimers of hydrogen bonded carboxylic acid in a number of organic solvents and finally gelatinize the
solvents. The gelation ability of each derivative was inspected. The morphologies of xerogels were
investigated by scanning electron microscope (SEM). The microstructure of aggregates was studied by
small angle X-ray diffraction (SA-XRD) and Fourier transform infrared spectroscopy (FT-IR). The results
reveal that the intermolecular hydrogen bonds between neighboring molecules are critical factor in the
process of organogelation.
