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

摘要

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 similar to 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.
