Diamagnetic metal sulfonates have been widely reported, while paramagnetic species are very rare, especially those that exhibit interesting magnetic and/or proton conduction properties. Herein, we report the synthesis, structure, magnetic, and proton-conducting properties of a hydrogen-bonded cobalt(II) organosulfonate complex. The coordination self-assembly CoII salts 8-quinolinesulfonic acid ligands affords mononuclear sulfonate featuring both coordinated noncoordinated sulfonic O atoms axial water molecules. Notably, units further connected by short S–O···H–O hydrogen-bonding interactions between SO3– H2O, leading to three-dimensional (3D) network. This exhibits superior thermal stability, as proved variable-temperature single-crystal powder X-ray diffraction thermogravimetric analysis (TGA) analysis. Variable-temperature variable humidity ac impedance spectroscopy indicated this cobalt is good superionic conductor with highest measured conductivity 1.5 × 10–3 S cm–1 at 90 °C under 97% relative humility, originating from 1D zigzag chains. In addition, field-induced slow relaxation was observed via dynamic susceptibility measurements. These results show not only first Co(II) single-ion magnet but also ″magnetic anisotropic ion-organosulfonate-coordinated water″ approach for design preparation bifunctional metalo-hydrogen-bonded organic framework (MHOF) materials.

Functionalized crystalline solids based on metal-organic frameworks (MOFs) enable efficient luminescence detection and high proton conductivity, making them crucial in the realms of environmental monitoring clean energy. Here, two structurally functionally distinct zinc-based MOFs, [Zn(TTDPa)(bodca)]·H2O (1) [Zn(TTDPb)(bodca)]·H2O (2), were successfully designed synthesized using 3,6-di(pyridin-4-yl)thieno[3,2-b]thiophene (TTDPa) 2,5-di(pyridin-4-yl)thieno[3,2-b]thiophene (TTDPb) as ligands, presence bicyclo[2.2.2]octane-1,4-dicarboxylic acid (H2bodca). Both 1 2 display a three-dimensional (3D) structure with 5-fold interpenetration, notably, forms larger one-dimensional pore measuring 17.16 × 10.81 Å2 size. Fluorescence experiments demonstrate that can function luminescent sensors for nitrofurantoin (NFT) nitrofurazone (NFZ) low limits, remarkable selectivity, good recyclability. A comprehensive analysis was conducted to investigate differing sensing effects compounds explore potential mechanisms. Additionally, at 328 K 98% relative humidity, exhibit conductivity values 2.13 10-3 4.91 S cm-1, respectively, suitable proton-conducting materials. Hence, integration monophasic 3D Zn-MOFs holds significant application intelligent multitasking devices.
