AI Article Synopsis
- - A new lanthanide complex, [Dy(phen)(PAA)](ClO), is created using 4-hydroxyphenyl acetate and 1,10-phenanthroline, exhibiting a dinuclear structure and a 2D supramolecular layer through π-π stacking interactions.
- - The complex displays distinct Dy(III) emission and shows characteristics of a single-molecule magnet (SMM) based on magnetic susceptibility measurements.
- - Under specific conditions (353 K and 100% relative humidity), the complex demonstrates significant proton conductivity, attributed to networks formed by phenolic groups and guest water molecules, making it the first dinuclear complex to exhibit photoluminescence, SMM behavior
Article Abstract
A new Dy-based complex, [Dy(phen)(PAA)](ClO) (), 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.
