Abstract
In this work, we describe the synthesis, characterization, and self-assembly properties of a new tetrathiafulvalene (TTF)-triglycyl low-molecular-weight (LMW) gelator. Supramolecular organogels were obtained in various solvents via a heating-cooling cycle. Critical gelation concentrations (CGC) (range approximate to 5-50 g/L) and thermal gel-to-sol transition temperatures (T-gel) (range ...
In this work, we describe the synthesis, characterization, and self-assembly properties of a new tetrathiafulvalene (TTF)-triglycyl low-molecular-weight (LMW) gelator. Supramolecular organogels were obtained in various solvents via a heating-cooling cycle. Critical gelation concentrations (CGC) (range approximate to 5-50 g/L) and thermal gel-to-sol transition temperatures (T-gel) (range approximate to 36-51 degrees C) were determined for each gel. Fourier transform infrared (FT-IR) spectroscopy suggested that the gelator is also aggregated in its solid state via a similar hydrogen-bonding pattern. The fibrillar microstructure and viscoelastic properties of selected gels were demonstrated by means of field-emission electron microscopy (FE-SEM) and rheological measurements. As expected, exposure of a model xerogel to I-2 vapor caused the oxidation of the TTF unit as confirmed by UV-vis-NIR analysis. However, FT-IR spectroscopy showed that the oxidation was accompanied with concurrent alteration of the hydrogen-bonded network.
