Sažetak
A major challenge in supramolecular chemistry is the synthesis of new materials that have improved properties for various uses in medical science, development of new biomaterials, sensors and many others [1]. Supramolecular chemistry has found interest in the synthesis of new materials because it provides a wide range of possibilities for generating new materials as self‐organized nanomaterials using non‐ covalent interactions such as hydrogen bonds, π‐ π stacking or Van der Waals forces. We have investigated the synthesis of new polymers [2]. For this purpose have developed new amino acid vinyl fumaric acid derivatives such as mono and di (vinyl‐amino acid) fumaramide. The novel supramolecular low molecular weight gelators are obtained (Figure 1). These compounds are capable of forming gels with various organic solvents. We investigated the possibility of polymerization in self‐ assembled gels induced by UV rays and gamma rays. The polymerization occurred in various gels. We have shown that small changes in the structure of compounds cause specific self‐ organization through non‐covalent interactions which effects on the reactivity of crosslinked molecules. The resulting self‐assemblies in different solvents are characterized by 1H, 13C, temperature dependent NMR and FTIR spectroscopy. Morphology of gel network and polymers are determined by TEM, SEM and AFM microscopy.
