A series of novel N-acyl-N'-aryl thiourea derivatives were designed and prepared with the aim to develop dual responsive receptors for anions and cations. The structure of the new products was confirmed by NMR spectroscopy (C and H), elemental analysis, and IR spectroscopy. Their thermal stability was studied by thermogravimetric analysis (TG) and it was found that these acyl thiourea derivatives are stable up to 160 °C. The ion recognition and sensing properties of the acyl thiourea compounds were investigated by UV-VIS absorption spectroscopy in organic media upon the addition of various salts. The UV-VIS studies revealed that these acyl thiourea derivatives are able to sense biological important ions such as fluoride and copper (II) ions.
设计并合成了一系列新型的 N-酰基-N'-芳基硫脲衍生物，旨在开发对阴离子和阳离子具有双重响应的受体。通过核磁共振波谱（C 和 H）、元素分析和红外光谱对新产物的结构进行了确认。通过热重分析（TG）研究了它们的热稳定性，发现这些酰基硫脲衍生物在 160°C 以下稳定。通过在有机溶剂中加入各种盐，通过紫外-可见吸收光谱研究了酰基硫脲化合物的离子识别和传感性能。紫外-可见研究表明，这些酰基硫脲衍生物能够感应生物重要的离子，如氟离子和铜（II）离子。
