A new series of boron complexes consisting of pyridine‐pyrazole ligands has been designed, synthesized and evaluated for its Raman activity using solid‐state Raman spectroscopy. The detailed surface‐enhanced Raman scattering (SERS) study of selected dye 2‐(3‐(pyridin‐4‐yl)‐1H‐pyrazol‐5‐yl) pyridine (P₄) on gold nanoparticles (AuNPs) of size 40 nm revealed that it can detect as small as the nanomole level with signal quality that is superior to structurally similar commercially available reporter molecules (RMs), rendering it a suitable RM for sensitive SERS nanotags.

硼配合物的设计和合成作为敏感SERS纳米标签的新拉曼报告分子

已经设计，合成了一系列由吡啶-吡唑配体组成的硼配合物，并使用固态拉曼光谱对其拉曼活性进行了评估。在大小为40的金纳米颗粒（AuNPs）上选择的染料2-（3-（吡啶-4-基）-1 H-吡唑-5-基）吡啶（P ₄）的详细表面增强拉曼散射（SERS）研究nm表明，它可以检测到纳摩尔级的分子，其信号质量优于结构相似的市售报告分子（RM），使其成为敏感SERS纳米标签的合适RM。
