Self-assembly of supramolecular homochiral structures in solutions of chiral biomimetics

Detected and describes in the present study the phenomenon of formation of homochiral supramolecular sets of vortices in dilute xerogels chiral biomimetics TFAAS metrically similar and specific macromolecular biological macroscopic helical structures. Each vortex with a characteristic scale of ~ 1 mm corresponds approximately to the rotational symmetry groups Sn, depending on the number of strings that have a common binding or emerging from one of nucleation and experiencing mutually agreed evasion. It is essential that the deviation direction is reversed by changing the chirality of the enantiomer does not depend on the type of solvent. In various mixtures of chiral compounds is observed as a weakening and strengthening of this trend. The result is an important confirmation of the authors proposed a synergistic rule that when the sign of the chirality of basic monomers is changed to the opposite sign of the chirality of them formed supramolecular helix. Regularity of a fundamental nature and executed as a trend in the hierarchies of macromolecular structures of DNA, proteins, polysaccharides. Keywords. Biomimetics, chirality, enantiomers, trifluoroacetylated aminoalcohols, strings, and supramolecular helical vortices.
