A well-studied supramolecular synthon, namely, secondary ammonium monocarboxylate (SAM), was exploited to generate a new series of organic salts derived from variously substituted phenylacetic acid and dicyclohexylamine as potential low-molecular-weight gelators. As much as 25 % of the SAM salts under study were gelators. The gels were characterized by rheology, and the morphology of the gel networks was studied by high-resolution electron microscopy. Single-crystal and powder XRD data were employed to study structure-property (gelation) correlations. One of the gels could adsorb a hydrophobic dye (Nile Red) more efficiently than that of a hydrophilic dye (Calcein) from dimethyl sulfoxide; this might provide useful clues towards the development of stain-removing gels.
一种经过充分研究的超分子合成子，即仲铵单羧酸盐（SAM），被用于制备一系列新的有机盐，这些有机盐由各种取代的苯乙酸和二环己胺衍生而来，作为潜在的低分子量凝胶剂。所研究的SAM盐中有多达25%是凝胶剂。通过流变学对凝胶进行了表征，并通过高分辨率电子显微镜研究了凝胶网络的形态。利用单晶和粉末XRD数据研究结构-性质（凝胶化）相关性。其中一种凝胶从二甲亚砜中吸附疏水性染料（尼罗红）的效率高于亲水性染料（钙黄绿素）；这可能为去污凝胶的开发提供有用线索。
