In this review, we demonstrate that the practical applications of a novel long-chain amidoamine derivative with a simple molecular structure (C18AA) are equivalent to or higher in number than those of supramolecules with complex molecular structures. Molecular assemblies of C18AA exhibit distinctive thermal responsiveness; namely, C18AA can form a gel with apolar organic solvents, while O/W emulsions of C18AA act as a heat-induced gelator that undergoes a phase transition from solution to gel upon heating. We also show that C18AA emulsions containing a quaternary ammonium salt develop an iridescent color over a specific temperature range. Further, molecular assemblies of C18AA serve as high-performance soft templates for the preparation of shape-controlled metal nanocrystals such as ultrathin Au nanowires and Pd nanowires.
在本综述中，我们证明了一种具有简单分子结构的新型长链酰胺胺衍生物（C18AA）的实际应用数量等同于或高于具有复杂分子结构的超分子。C18AA的分子聚集体表现出独特的热响应性；也就是说，C18AA可与非极性有机溶剂形成凝胶，而C18AA的水包油乳液则作为热诱导凝胶剂，加热时会发生从溶液到凝胶的相变。我们还表明，含有季铵盐的C18AA乳液在特定温度范围内会呈现彩虹色。此外，C18AA的分子聚集体可作为高性能软模板，用于制备形状可控的金属纳米晶体，如超薄金纳米线和钯纳米线。
