The low molecular weight ($\mathit{Mr}\sim 200$ Da) chiral N-trifluoroacetylated $\alpha$-aminoalcohols (TFAAAs) are able for gelate various organic solvents and water in very low concentrations ($\sim {10}^{-3}$ M). The gelation was not observed in the racemic solutions or solution of achiral TFAAA. The gelation is temperature-reversible and demonstrates the memory effect. The gel scaffold is composed of thin supramolecular elements (strings) having a helical structure. The thinnest (elementary) strings have a crystalline, highly ordered structure and braid together to form thicker elements. The sign of the helicity changes with the growing of the strings in course of the gelation process, so that the thicker strings have the opposite helicity as compared to thiner ones. We provide a theoretical description of the strings growing process.

低分子量（$\mathit{先生}〜200$ Da）手性N-三氟乙酰化 $\alpha$-氨基醇（TFAAAs）能够以非常低的浓度凝胶化各种有机溶剂和水（$〜{10}^{--3}$ M）。在外消旋溶液或非手性TFAAA溶液中未观察到凝胶化。胶凝是温度可逆的，并显示出记忆作用。凝胶支架由具有螺旋结构的薄的超分子元件（线）组成。最细的（基本）弦具有结晶的，高度有序的结构，并且编织在一起以形成较厚的元素。在胶凝过程中，螺旋度的符号随字符串的增长而变化，因此，较细的字符串与较细的字符串具有相反的螺旋度。我们提供了琴弦生长过程的理论描述。
