设计并合成了由三唑连接的基于二茂铁的萘或喹啉受体1-4。在水环境中系统地研究了它们对金属阳离子的识别性能。添加 1 当量后。 Cu2+离子、受体1(C23H19FeN3O)和2(C22H18FeN4O)表现出荧光关闭、吸收增强和颜色变化。同时，受体1添加1当量后也会引起氧化还原电位的扰动。 Cu2+离子。因此，受体1和2作为Cu2+的肉眼化学传感器和荧光探针，不受其他离子干扰，检测限低。此外，receptor1也可以被认为是Cu2+的电化学传感器，具有良好的灵敏度和选择性。然而，增加分子灵活性导致受体 3(C24H21FeN3O) 和 4(C23H20FeN4O) 的离子识别选择性较低。此外，该系列化合物无毒，受体1具有一定的抗菌活性。
Ferrocene–based naphthalene or quinoline receptors1–4linked by triazole were designed and synthesized. Their recognition properties of metal cations have been investigated systematically in aqueous environment. Upon addition 1 equiv. of Cu2+ion, receptors1(C23H19FeN3O) and2(C22H18FeN4O) showed fluorescent turn-off, enhanced absorption and color variations. At the same time, receptor1also caused the perturbation of redox potential after addition 1 equiv. of Cu2+ion. Therefore, receptors1and2behaved as naked-eye chemosensors and fluorescent probes for Cu2+without interference by other ions and with low detection limit. In addition, receptor1could also be considered electrochemical sensor for Cu2+having excellent sensitivity and selectivity. However, increasing the molecules flexibility resulted in the lower selectivity of ion recognition in the case of receptors3(C24H21FeN3O) and4(C23H20FeN4O). Furthermore, this series of compounds were nontoxicity and receptor1exhibited certain antibacterial activity.
