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