COLLECTIVE NATURE OF SPONTANEOUS FORMATION OF STRINGS IN HOMOCHIRAL SOLUTIONS

Abstract

Using optical microscopy we calculated the
number of strings, formed on a glass substrate with the free
dry samples (drops) by evaporating the solvents from a number
of homochiral solutions of trifl uoro acetylated amino alcohols
in various organic solvents, on a set of optical fi elds.
From the statistical analysis of the distribution of strings on the
investigated optical fi elds the collective nature of their formation
was identifi ed. The characteristic scale of their correlated
formation [(200 - 600) ƒm] was found. The likely mechanism
of the detected correlations was considered. As an illustration
of the correlated formation of strings, we described the
frequent phenomenon of paired strings.
