Podand triazole-linked gold nanoparticles were designed via an in situ'click' reaction. The resulting gold nanoparticles were characterized by UV-vis spectroscopy, FT-IR spectroscopy, transmission electron microscopy (TEM). Podand triazole-linked gold nanoparticles were utilized as colorimetric probes for Pb(2+)via Pb(2+)-induced gold nanoparticle aggregation which incorporates two podand molecules from different nanoparticles forming an intermolecule type of association. Moreover, the application of the resulting gold nanoparticles to evaluate the exceeding standard of lead ions in drinking water and leaded paint was investigated.
通过原位“点击”反应设计了含卟啉三唑链接的金纳米粒子。通过紫外可见光谱、傅里叶变换红外光谱、透射电子显微镜（TEM）对得到的金纳米粒子进行了表征。含卟啉三唑链接的金纳米粒子被用作 Pb(2+)的比色探针，这是由于 Pb(2+)诱导的金纳米粒子聚集，其中两个来自不同纳米粒子的卟啉分子形成分子间类型的缔合。此外，还研究了所得金纳米粒子在评估饮用水和含铅涂料中铅离子超标方面的应用。
