通过使用铜催化的点击反应，已经制备了许多单取代（3、4、6、8、9、11和13）和二取代（15和16）二茂铁衍生的三唑，并进行了充分表征。点击反应的多功能性使得二茂铁-三唑核得以修饰，额外的取代基表现出不同的光电化学性质。传感研究中最显着的特征是，在 F–、AcO–、H2PO4– 和 HP2O73– 阴离子存在的情况下，受体 3、6、15 和 16 的二茂铁/二茂铁氧化还原对的氧化峰经历了前所未有的阴极位移，而受体 11 和 16 则充当 Hg2+ 的双氧化还原和光学选择性分子传感器。 阳离子。分离的[63·Ni2+]配合物已通过X射线分析进行了表征。
A number of monosubstituted (3, 4, 6, 8, 9, 11, and 13) and disubstituted (15 and 16) ferrocene-derived triazoles have been prepared, by using the copper-catalyzed click reaction, and fully characterized. The versatility of the click reaction enables the decoration of the ferrocene-triazole core, with additional substituents displaying different optoelectrochemical properties. The most salient features derived from the sensing studies are that receptors 3, 6, 15, and 16 undergo unprecedented cathodic shifts of the oxidation peak of the ferrocene/ferrocenium redox couple in the presence of F–, AcO–, H2PO4–, and HP2O73– anions, whereas receptors 11 and 16 behave as dual redox and optically selective molecular sensors for Hg2+ cations. The isolated [63·Ni2+] complex has been characterized by X-ray analysis.
