提出了一种温和、简便的一步合成策略,用于制备尺寸和形状受控的银纳米颗粒(AgNP)。这些 AgNP 的高度尺寸和形状控制是通过使用由中心间苯二酚醚核心支撑的三唑糖配体来实现的。在 Tollens 试剂作为银源存在的情况下,三唑和间苯二酚醚核均介导 AgNP 制备的成核、生长和钝化阶段。动力学和 1H NMR 滴定数据描述了 Tollens 试剂和这些配体之间相互作用的性质。
A mild, facile one-step synthetic strategy for the preparation of size-and shape-controlled silver nanoparticles (AgNPs) is presented. The high degree of size-and shape-control of these AgNPs is achieved by the use of triazole sugar ligands scaffolded by a central resorcinol ether core. Both the triazoles and the resorcinol ether core mediate the nucleation, growth, and passivation phases of the preparation of AgNP in the presence of the Tollens reagent as the silver source. Kinetic and 1H NMR titration data is presented describing the nature of the interactions between the Tollens reagent and these ligands.
