The aim of the study was to create and study the properties of organized molecular systems based surfactants, which act as effective nanoreactors and nanocontainers, study their properties and evaluation of potential applications in a series of model reactions. Methods - one-dimensional (1H, 31R) and two-dimensional (1H-1H, 1H-31R) NMR spectroscopy, elemental analysis, UV-Vis-spectroscopy, potentiometry, tensiometry, optical microscopy, differential scanning calorimetry. With regard to the principles of molecular economy developed and optimized methods for the synthesis of surfactant structures of variable head group, counter ion, and the length of the hydrophobic moiety. Physical and chemical properties of supramolecular systems based surfactants derived were studied and the perspectives for their use for a number of catalytic transformations where the effect of enhancement the process provides the ability to act as a surfactant nanocontainer for reagents were estimated. On the example of the model system were determined the reaction products of cleavage of typical of organophosphorus ecotoxicant, 4-nitrophenyl diethyl phosphonate to lead the basis for setting details of the mechanism of cleavage of acyl-containing substrates in the micellar catalytic systems. Structural and phase transitions in mono- and dicationic surfactants was studied as a factor regulating their thermodynamic stability and reactivity. The studied surfactants we demonstrated t tend to self-organisation in aqueous solution as well as in solid state. The results have scientific significance for the development of the theory of the structure and properties of organized molecular systems. The practical importance is the ability to use (i) obtained micellar systems as an effective media for conducting cross-coupling reactions and for cleavage of ecotoxic substrates; b) designing liquid crystallline systems with variable viscosity.
