We used tip-enhanced Raman spectroscopy (TERS) to examine plasmon-driven dimerization of 4-bromothiophenol (4-BTP) into thiophenol (TP) and 4,4'-biphenyldithiol (4,4'-BPDT) on Au and Ni@AuNPs. TERS revealed that cross-coupling of these molecular reactants into 4,4'-BPDT occurred primarily on Ni nano islands rather than the surrounding Au on the surface of Ni@AuNPs.
我们使用针尖增强拉曼光谱（TERS）来研究在金和镍@金纳米颗粒上，等离激元驱动4-溴硫酚（4-BTP）二聚化为硫酚（TP）和4,4'-联苯二硫醇（4,4'-BPDT）的过程。TERS显示，这些分子反应物交叉偶联形成4,4'-BPDT的过程主要发生在镍@金纳米颗粒表面的镍纳米岛上，而非周围的金上。
