| Summary: | 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<sup>III</sup>-SMM together with luminescent and proton-conducting properties, [Dy<sub>2</sub>(1-tza)<sub>4</sub>(phen)<sub>4</sub>]∙(ClO<sub>4</sub>)<sub>2</sub>∙(H<sub>2</sub>O)<sub>2</sub> (<b>1</b>, 1-tza = 2-(1H-tetrazol-1-yl)acetic, phen = 1,10-phenanthroline), was prepared and structurally characterized. Complex <b>1</b> features a dinuclear structure bridged by carboxylate oxygen atoms of the 1-tza<sup>−</sup> ligands, and its supramolecular network contains a 1D stacking channel. Complex <b>1</b> exhibits strong room-temperature Dy<sup>III</sup> characteristic emissions and SMM behaviors. In addition, complex <b>1</b> shows a moderate proton conductivity with 4.00 × 10<sup>−6</sup> S cm<sup>−1</sup> 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 <b>1</b>. |
