Abstract

A novel ruthenium(II) polypyridyl complex bearing 1,8-naphthyridine was successfully designed and synthesized. This complex was fully characterized by EI-HRMS, NMR, and elemental analyses. The recognition properties of the complex for various metal ions were investigated. The results suggested that the complex displayed high selectivity and sensitivity for Cu and Fe ions with good anti-interference in the CHCN/HO (1:1, /) solution. The fluorescent chemosensor showed obvious fluorescence quenching when the Cu and Fe ions were added. The detection limits of Cu and Fe were 39.9 nmol/L and 6.68 nmol/L, respectively. This study suggested that this Ru(II) polypyridyl complex can be used as a high selectivity and sensitivity fluorescent chemosensor for Cu and Fe ions.

摘要

一种新型的钌（II）多吡啶配合物，带有 1,8-萘啶，成功地被设计和合成。该配合物通过 EI-HRMS、NMR 和元素分析进行了全面的表征。研究了该配合物对各种金属离子的识别性能。结果表明，该配合物在 CHCN/HO（1:1，/）溶液中对 Cu 和 Fe 离子具有高选择性和灵敏度，并且具有良好的抗干扰性。当加入 Cu 和 Fe 离子时，荧光化学传感器显示出明显的荧光猝灭。Cu 和 Fe 的检测限分别为 39.9 nmol/L 和 6.68 nmol/L。本研究表明，该 Ru(II) 多吡啶配合物可作为一种高选择性和灵敏度的荧光化学传感器，用于 Cu 和 Fe 离子。
