commercial and fundamental applications. SERS often relies on ligands, usually thiols, bound to a noble metal surface. The difficulty of straightforward thiol synthesis combined with their instability on surfaces highlights the need for alternative ligand design. We present the first example of SERS utilizing N-heterocyclic carbene ligands. A general three step synthesis is presented for functionalized NHC-CO2
表面增强拉曼光谱 (SERS) 支持广泛的商业和基础应用。SERS 通常依赖于与贵金属表面结合的配体,通常是硫醇。直接硫醇合成的困难加上它们在表面上的不稳定性突出了对替代配体设计的需求。我们展示了第一个利用 N-杂环卡宾配体的 SERS 示例。介绍了功能化 NHC-CO2 加合物的一般三步合成。这些配体在无溶剂和无碱条件下沉积在 SERS 活性金膜纳米球基底 (AuFON) 上,从而防止结垢。发现所得薄膜坚固且能够进行合成后修饰。
