Coordination chemistry was applied to deposit pyridine-functionalized gold nanoparticles on silicon substrates. The particles were synthesized through the Brust/Schiffrin route with a subsequent ligand exchange reaction yielding well-defined particles of two different sizes. Multilayer deposition was carried out on a pyridine-terminated SAM, anchored on a hydroxyl-terminated silicon surface. Analogously, Hunter/Vögtle-type tetralactam macrocycle multilayers were deposited as well as mixed layers containing both either in an alternating sequence or as a macrocycle multilayer with a terminating nanoparticle layer. These composite layers were examined with respect to their ability to bind squaraine axles in the macrocycle cavities. The amount of guest bound is higher for the composite layer with alternating macrocycles and nanoparticles.
配位化学被应用于将吡啶功能化的金纳米粒子沉积在硅衬底上。这些粒子是通过 Brust/Schiffrin 路线合成的,随后进行配体交换反应,得到两种不同尺寸的定义明确的粒子。多层沉积在吡啶封端的 SAM 上进行,SAM 固定在羟基封端的硅表面上。类似地,还沉积了 Hunter/Vögtle 型四元内酰胺大环多层,以及包含两者的混合层,这些混合层以交替序列或以具有终止纳米粒子层的大环多层的形式存在。这些复合层被检测其在大环腔中结合方酸轴的能力。具有交替大环和纳米粒子的复合层结合的客体数量更多。
