Development of new fumaramide gelators and transcription gels in polymers

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 others1. 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 polymers2. For this purpose have developed new amino acid vinyl fumaric acid derivatives such as mono(vinyl-amino acid) fumaramide. The novel supramolecular low molecular weight gelator is obtained (Figure 1.). These compounds are capable of forming gels with various organic solvent. We investigated the possibility of polymerization in gels induced by UV rays. The polymerization only occurred in acetonitrile gel, we have shown that small changes in the structure of compound cause specific self- organization through non-covalent interactions which effects on the reactivity of crosslinked molecules. The resulting self- assembles 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.
