As efficient alternative renewable energy resources, proton-exchange membrane fuel cells (PEMFCs) have received immense attention where proton-conducting materials act as PEMs for proton migration. The recent past has witnessed considerable progress in the use of metal–organic frameworks (MOFs) and coordination polymers (CPs) solid-state conductors (SSPCs) due to their structural superiority architectural diversity. In order impart conductivity, a variety intrinsic extrinsic sources been installed onto these frameworks; however, reports on conduction metal-coordinated water molecules solely by virtue enhanced acidity are largely unexplored. key examples driven coordinated discussed this Perspective present some unique features MOFs CPs SSPCs, displaying wide range conductivity. scope works with plausible design principles that urgently required be investigated is also highlighted.

The sensing and monitoring of toxic oxo-anion contaminants in water are significant importance to biological environmental systems. A rare hydro-stable SIFSIX metal-organic framework, SiF6 @MOF-1, {[Cu(L)2 (H2 O)2 ]·(SiF6 )(H2 O)}n , with exchangeable SiF62- anion its pore is strategically designed synthesized, exhibiting selective detection Cr2 O72- an aqueous medium having high sensitivity, selectivity, recyclability through fluorescence quenching phenomena. More importantly, the recognition ion exchange mechanism unveiled rarely explored single-crystal-to-single crystal (SC-SC) fashion well-resolved structures. thorough SC-SC study interfering anions (Cl- F- I- NO3- HCO3- SO42- SCN- IO3- ) revealed no such transformations take place, as per line studies. Density functional theory calculations that despite a lesser binding affinity, shows strong orbital mixing large driving forces for electron transfer than thus enlightens mechanism. This work inaugurates usage MOF toward application domain under where hydrolytic stability prime concern their plausible implementation sensor materials.

Multifunctional materials, which exhibit diverse physical properties, are candidates for the new generation of smart devices that realize many tasks simultaneously. Particular attention is given to single-phase multifunctional materials offer effects induced by coupling between introduced properties. Complexes lanthanide(3+) ions an attractive source multifunctionality since they combine luminescent functionalities related their f-f or d-f electronic transitions with magnetic anisotropy originates from spin-orbit and crystal-field effects. The resulting single-molecule magnets (SMMs) link area functional luminophores, applicable in light-emitting diodes sensing, field molecular magnets, high-density data storage, additional advantages, e.g., fruitful magneto-optical correlations switching emission a field. It was recently shown lanthanide SMMs can provide richly expanded towards sensitivity solvent exchange, temperature, light, as well electrical such super-ionic conductivity ferroelectricity, non-centrosymmetricity- chirality-related effects, second-harmonic circularly polarized luminescence. Here, we discuss pioneering reports on use SMMs, emphasis our contribution relying functionalization 4f metal complexes through insertion into heterometallic coordination compounds.

Achieving high intrinsic proton conductivity is essential for the development of stable conductors in exchange membrane fuel cells. Herein, an ionic liquid (IL) with a hydrosulfate anion, imidazole ring, and sulfonate group beneficial to transfer was used functionalize metal–organic framework (MOF-808) by replacing formates coordinated Zr. The obtained MOF-808-IL exhibits 1.28 × 10–1 S cm–1 at 60 °C 100% relative humidity (RH), which exceeds those most MOF-based conductors. Moreover, mechanism has been elucidated combination crystal structure variable temperature Fourier transform infrared spectra. This study provides strategy achieving ultrahigh model analyzing conducting mechanism.

Proton conductors are essential functional materials with a wide variety of potential applications in energy storage and conversion. In order to address the issues low proton conductivity poor stability conventional conductors, simple valid ion-exchange method was proposed this study for introduction stable ultrahigh layered rare earth hydroxides (LRHs). Test analyses by solid-state nuclear magnetic resonance, Fourier transform infrared spectroscopy, powder X-ray diffraction revealed that exchange H2PO4– not only does disrupt structure LRHs, but also creates more active sites channels necessary transport, thereby creating high-performance conductor (LRH-H2PO4–). By utilizing method, LRHs can be significantly enhanced from level an (>10–2 S·cm–1), while maintaining excellent long-term stability. Moreover, through methodically manipulating guest ions molecules housed within interlayers comprehensive explanation has been presented regarding proficient mechanism conduction LRH-H2PO4–. As result, investigation presents feasible available approach advancing conductor.
