Summary: Six isostructural three-dimensional Ln(III)-organic frameworks were fabricated using a multifunctional ligand H3MIDC, exhibiting humidity- and temperature-dependent proton conductivity. The proton conductivity systematically enhances with decreasing ionic radius, suggesting that lanthanide contraction tactics effectively regulate proton conductivity. These Ln-MOFs show promising potential for future applications due to their water and electrochemical stability.

Summary: In this study, a novel phthalocyanine-based nickel-bis(dithiolene) (NiS4)-linked 2D c-MOF (denoted as Ni2[CuPcS8]) was reported, which exhibited outstanding pseudocapacitive properties in 1 M TEABF4/acetonitrile. The Ni2[CuPcS8] electrode demonstrated a record-high specific capacitance among reported 2D c-MOFs in non-aqueous electrolytes (312 F g-1) and remarkable cycling stability (93.5% after 10,000 cycles). The unique electron-storage capability of Ni2[CuPcS8] was attributed to its localized lowest unoccupied molecular orbital (LUMO) over the nickel-bis(dithiolene) linkage, enabling efficient delocalization of injected electrons without inducing apparent bonding stress. The Ni2[CuPcS8] anode was used in an asymmetric supercapacitor device, delivering a high operating voltage of 2.3 V, a maximum energy density of 57.4 Wh kg-1, and ultralong stability over 5000 cycles.

Summary: Solventless mechanochemical synthesis by manual grinding was used to successfully synthesize organic proton conducting salts imidazole-succinic acid and imidazole-glutaric acid. This method allows for crystallization and produces phase-pure compounds. The compounds exhibit different electrical conducting behavior and activation energies compared to single crystals obtained from a solution method. The differences in conducting properties are attributed to defects and structural disorder introduced by mechanochemical grinding, indicating the strong capability of this method for tuning conductivities. Additionally, complete deuteration of the organic salts is achieved, highlighting the potential for large-scale industrial production of organic salts through mechanochemical synthesis.

Summary: Two cobalt(II) halide complexes, [Co(Htrz)Cl-2](n) and {[Co(Htrz)(2)(trz)]BF4}(n), with 1,2,4-triazole as a ligand, were synthesized. The structures of these complexes were determined using extended x-ray absorption fine structure (EXAFS) and powder x-ray diffraction (XRD). Both complexes form one-dimensional polymeric chains with Co center dot center dot center dot Co distances of 3.3521(2) A and 3.8629(2) A, respectively. The analysis of Co L-II,L-III-edge XAS indicates that the Co(II) in these complexes are in a high spin state with t(2g)(5)e(g)(2) configuration. The broken-symmetry DFT calculations reveal that the antiferromagnetic coupling state of Co center dot center dot center dot Co is the most stable state in both complexes, with coupling constants of -0.32 cm(-1) and -3.70 cm(-1) for complexes 1 and 2, respectively. The antiferromagnetic interaction is achieved through triazole ligands based on the distances of Co center dot center dot center dot Co and coupling constants.

Summary: This study focuses on the synthesis and properties of CuFeS2 chalcogenides, investigating their catalytic activity in the decolorization of rhodamine B (RhB) and antibacterial activity. CuFeS2 prepared at 250 degrees C (CuFeS2-250) showed higher crystallinity, Fe2+ concentration on the surface, and a Fenton-like oxidation process with Na2S2O8, exhibiting a 99.0% RhB decolorization efficiency within 7 min. CuFeS2-250/Na2S2O8 also demonstrated excellent antibacterial activity (>90.4% eradication rate within 120 min) against Escherichia coli, Staphylococcus aureus, and methicillin-susceptible S. aureus. These findings highlight the enhanced catalytic activity of CuFeS2-250 and its potential for industrial applications in wastewater treatment.

Summary: New palladium complexes with N-heterocyclic carbene (NHC) ligands derived from nitron and its derivatives were synthesized and their structures were determined by X-ray diffraction. Among these complexes, the palladium complex with a monodentate NHC ligand derived from nitron showed the highest catalytic activity in the Mizoroki-Heck coupling reaction. Theoretical calculations explained the importance of a robust Pd-C bond and the π-accepting property of the NHC ligand for enhanced catalytic activity. Notably, the activation of the preformed palladium(0) complex was much faster compared to its palladium(II) counterpart. Palladium(0) NHC complexes obtained from nitron and its derivatives exhibited high efficacy in catalyzing the Mizoroki-Heck coupling reaction involving aryl chlorides.
