and Pb2+ studied in 1,4-dioxane/water (70:30, v/v). Both ligands L1 and L2 are difunctionalised receptors containing redox-active (ferrocene) and fluorescent (anthracene) signalling subunits. The crystal structures of [H2L1][PF6]2 and [CuL2][PF6]2 were determined by single-crystal X-ray procedures. Potentiometric experiments in dioxane/water (70:30, v/v; 0.1 M KNO3; 25.0 ± 0.1 °C) for L1 and L2 allowed
新配体 13-anthrylmethyl-7-ferrocenylmethyl-1,4,10-trioxa-7,13-diaza-cyclopentadecane (L1) 和 1-anthrylmethyl-4,8,11-ferrocenylmethyl-1,4,8,11-四氮杂环十四烷 (L2) 已被合成、表征,并在 1,4-二恶烷/水 (70:30, v/v) 中研究了它们作为金属阳离子 Ni2+、Cu2+、Zn2+、Cd2+、Hg2+ 和 Pb2+ )。配体 L1 和 L2 都是双功能化受体,含有氧化还原活性(二茂铁)和荧光(蒽)信号亚基。[H2L1][PF6]2 和 [CuL2][PF6]2 的晶体结构是通过单晶 X 射线程序确定的。L1 和 L2 在二恶烷/水 (70:30, v/v; 0.1 M KNO3; 25.0 ± 0.1 °C) 中进行的电位实验可以测定 Cu2+ 和
