Morphological characterization of the catanionic amphiphiles

Sažetak
Contemporary life is very complex. The spontaneous transformation of non-living matter to living entities is considered to be a result of a continuous evolutional and prebiological process during which the molecular and supramolecular complexity increased. The field of supramolecular chemistry, to which the self-association of amphiphilic molecules belongs, may contribute to the development of research and different applications in the fields of biology, medicine and chemistry, and to the scientific understanding of life, health, diagnostic and therapy. Solid catanionic amphiphils can be synthesized by interaction between amphiphils or similar amphiphilic biomolecular compounds of the opposite electrostatic charge in aqueous solutions. Arrangement and preferred shape of catanionic supramolecular aggregates are consequence of primarily electrostatic interactions and preferred hydrophilic and hydrophobic orientation of the abovementioned combination of molecules. Analysis of the morphological characteristics of many different catanionic lyotropic and thermotropic liquid crystals allows association of their chemical structures with related mesostructures and corresponding physicochemical properties.
