Sažetak
A recent study in the field of supramolecular gels resulted in the development of recognizable areas in materials chemistry with an emphasis on self- organizing soft materials. They have a great opportunity for specific applications in various fields, such as the chemistry of materials, pharmaceutical, food cosmetic industry, or tissue engineering and regenerative medicine. Polymerization can improve the mechanical properties of supramolecular gels, or prepared specific polymer materials. In order to achieve the "solid-state" reaction within the gel network, is necessary to meet the special requirements of the self-association of gelators molecules. This especially refers to the distance and position of functional groups. Our attention was focused on the phenomenon of self-association in gels. The Leu, Val, and Phe, bis(amino acid) fumaramides derivatives shown in Figure 1. were synthesized and characterized. Furthermore, appropriate mono (vinyl amino acid) fumaramide derivatives with long aliphatic chains on the one end were synthesized and characterized. By the process of self-association, these compounds can form gels with various organic solvents and water and solvent mixtures. When irradiated, some gel networks polymerize. The polymerization (covalent crosslinking) was induced by photo and gamma radiation. We have shown that small changes in the structure of compounds cause specific self- association through non-covalent interactions which affect the reactivity of crosslinked molecules. Gelators with two polymerized functional groups experienced successful "solid- state" polymerization reactions with transcription of the morphology of the initial self-assembled gel networks gel network into polymers.
