Multifunctional materials bearing photoluminescence, single-molecule magnet (SMM) behavior, and proton conduction have been particularly attractive for various promising applications in optics, molecular spintronics, high-density data storage, and fuel cells. However, these kinds of multifunctional systems have rarely been reported. Herein, a Dy-SMM together with luminescent and proton-conducting properties, [Dy(1-tza)(phen)]∙(ClO)∙(HO) (, 1-tza = 2-(1H-tetrazol-1-yl)acetic, phen = 1,10-phenanthroline), was prepared and structurally characterized. Complex features a dinuclear structure bridged by carboxylate oxygen atoms of the 1-tza ligands, and its supramolecular network contains a 1D stacking channel. Complex exhibits strong room-temperature Dy characteristic emissions and SMM behaviors. In addition, complex shows a moderate proton conductivity with 4.00 × 10 S cm at 37 °C and 100% R.H. (R.H. = Relative Humidity), which may be ascribed to the 1D-extended H-bonds in the 1D stacking channel of .
具有光致发光、单分子磁体(SMM)行为和质子传导功能的多功能材料,对于光学、分子自旋电子学、高密度数据存储和燃料电池等各种有前景的应用特别有吸引力。然而,这类多功能体系鲜有报道。在此,制备并对结构进行了表征的一种具有发光和质子传导性质的Dy-SMM,即[Dy(1-tza)(phen)]∙(ClO)∙(HO)(其中1-tza = 2-(1H-四氮唑-1-基)乙酸,phen = 1,10-菲咯啉)。配合物具有由1-tza配体的羧酸根氧原子桥连的双核结构,其超分子网络包含一个一维堆积通道。配合物在室温下表现出强烈的Dy特征发射和SMM行为。此外,配合物在37 °C和100%相对湿度(R.H. = 相对湿度)下显示出4.00 × 10 S cm的适度质子传导率,这可能归因于其在一维堆积通道中的一维扩展氢键。
