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 (1)H NMR titration data is presented describing the nature of the interactions between the Tollens reagent and these ligands.
本文提出了一种温和、简便的一步法合成策略，用于制备尺寸和形状可控的银纳米粒子（AgNPs）。这些 AgNPs 的高度尺寸和形状可控性是通过使用三唑糖配体与中心间苯二酚醚核支架来实现的。在 Tollens 试剂作为银源的存在下，三唑和间苯二酚醚核介导了 AgNP 制备的成核、生长和钝化阶段。本文还介绍了描述 Tollens 试剂与这些配体之间相互作用性质的动力学和（1）H NMR 滴定数据。
