Initiation of the formation of chiral strings: Dimension of formation domain, microstructure, and nucleation mechanism

Abstract

The initiation of the formation of strings in low concentration chiral solutions was experimentally studied. The domains of initiation were classified according to dimensions: (0-3)D. The dipole-dipole mechanism of the formation of anisotropic nucleation in a mesophase was considered. The role of dispersion interactions in the assembly of supramolecular stacks was estimated at ~0.3-0.4 eV. The threshold values of string formation in chiral mixtures were determined. A phenomenon of the formation of paired strings was established and characterized.
