A new Dy-based complex, Dy(phen)(PAA) (), was obtained by using 4-hydroxyphenyl acetate (HPAA) as a ligand and 1,10-phenanthroline as an auxiliary ligand. Complex shows a dinuclear structure and a 2D supramolecular layer constructed by π-π stacking interactions. The complex displays a characteristic Dy(III) emission. Moreover, magnetic susceptibility measurements revealed that exhibits a single-molecule magnet (SMM) behavior. In addition, it also shows a proton conductivity of 1.08 × 10 S cm under 353 K and 100% relative humidity conditions, which is mainly assigned to H-bonded networks formed by the undeprotonated and uncoordinated phenolic groups of HPAA ligands and guest water molecules. Remarkably, is the first example of a dinuclear complex showing photoluminescence, SMM behavior, and proton conduction.
通过使用对羟基苯乙酸（HPAA）作为配体和1,10-菲咯啉作为辅助配体，得到了一种新型的基于镝的配合物Dy(phen)(PAA)（）。配合物呈现出双核结构以及由π-π堆积相互作用构建的二维超分子层。该配合物表现出特征性的Dy(III)发射。此外，磁化率测量表明 表现出单分子磁体（SMM）行为。此外，在353 K和100%相对湿度条件下，它还显示出1.08×10 S cm的质子传导率，这主要归因于由HPAA配体未质子化和未配位的酚基以及客体水分子形成的氢键网络。值得注意的是， 是首个呈现光致发光、SMM行为和质子传导的双核配合物实例。
