Abstract

In this project, terpyridine compound including aromatic moiety (L^TPY−1naph) was synthesized and characterized. In order to study the sensing properties, “Zinc(II) complexes” [ZnBr₂ (L^TPY−1naph)] was synthesized and characterized. To investigate the sensing properties of the complex toward sulfur aromatic pollutants, 2.8 × 10^–5 M solution of the complexes in the presence of 1 to 10 ppm of the pollutants was studied. The sensing response of the complex toward benzene toluene and phenyl-methyl sulfoxide is positive, whereas the sensing response of the complex toward phenyl-methyl sulfide, thiathrene, thiophene, and thiophenol. The reason for the positive response of the complex to some of these pollutants is a lone pair π…π between a lone pair of sulfur and an aromatic moiety of the terpyridine ligand.

含芳基锌配合物的三吡啶配体：合成及传感性能研究

本课题合成并表征了含芳香部分（LTPY−1naph）的三联吡啶化合物。为了研究其传感性能，合成了“锌（II）配合物”[ZnBr2 (LTPY−1naph)]并对其进行了表征。为了研究配合物对含硫芳香族污染物的传感性能，研究了配合物在含有1 ~ 10 ppm污染物的2.8 × 10 - 5 M溶液中对含硫芳香族污染物的传感性能。该配合物对苯甲苯和苯基甲基亚砜的传感响应为正，而对苯基甲基硫醚、噻吩、噻吩和噻吩的传感响应为正。配合物对这些污染物的积极反应的原因是孤对π…π之间的孤对硫和三吡啶配体的芳香部分。图形抽象
