Abstract

A novel application of an organometallic platinum (II) complex, K[Pt(dfppy)(p-MeC₆H₄)(CN)], is reported for the selective detection of lead ion using a surface plasmon resonance imaging (SPRi) platform. The complex was synthesized via the reaction of [Pt(dfppy)(p-MeC₆H₄)(SMe₂)] with KCN in a methanol–water medium and characterized by NMR, FT-IR, and UV–vis spectroscopies. The resulting yellow complex was drop-cast onto a gold-coated glass substrate to form the sensing layer, whose morphology and optical response were analyzed using scanning electron microscopy (SEM) and SPRi techniques, respectively. The sensing behavior of the fabricated layer was evaluated toward Pb²⁺, Hg²⁺, Zn²⁺, and Ni²⁺ ions at various complex concentrations (10⁻³, 10⁻⁴, and 10⁻⁵ M). Among the tested ions, the sensor exhibited the strongest response to Pb²⁺, with a detection limit as low as 0.05 ppm. This study reports a simple and effective approach for plasmonic detection of lead ions with high sensitivity and selectivity using a cyclometalated platinum(II) complex.

基于表面等离子体共振传感器的有机金属铂（II）配合物铅检测

报道了一种有机金属铂（II）配合物K[Pt(dppy)(p-MeC6H4)(CN)]的新应用，用于使用表面等离子体共振成像（SPRi）平台选择性检测铅离子。该配合物由[Pt(dfppy)(p-MeC6H4)(SMe2)]与KCN在甲醇-水介质中反应合成，并通过NMR、FT-IR和UV-vis光谱对其进行了表征。将得到的黄色配合物滴铸到镀金玻璃基板上形成传感层，分别使用扫描电子显微镜（SEM）和SPRi技术分析其形貌和光学响应。在不同络合物浓度（10−3、10−4和10−5 M）下，评价了制备层对Pb2+、Hg2+、Zn2+和Ni2+离子的传感行为。其中，传感器对Pb2+的响应最强，检测限低至0.05 ppm。本研究报告了一种简单有效的等离子体检测铅离子的方法，该方法使用环金属化铂（II）配合物具有高灵敏度和选择性。
