摘要: In this work, we demonstrate that coordination interactions between Fe3+ and cucurbit[7]uril (CB[7]) can be utilised to build up defined nanoscale spacing layers in metallic nanosystems. We begin by characterising the layer-by-layer deposition of CB[7] FeCl3·6H2O through use a Quartz-Crystal Microbalance (QCM) contact angle measurements. then apply layered structure accurately control spacing, thus optical properties, gold nanoparticles Nanoparticle-on-Mirror (NPoM) structure, which is demonstrated via normalising plasmon resonance spectroscopy.
