Summary: The synthesis of two azadipyrromethene complexes with zinc(II) and cobalt(II) is described. The complexes were characterized using UV-Vis spectrophotometry, mass spectrometry, and NMR spectroscopy. The complexes exhibited high molar absorptivities in the visible region, with the zinc(II) complex showing a single long-wavelength band and the cobalt(II) complex accompanied by a shoulder. X-ray crystallography revealed minimal influence of the metal(II) ion on the molecular structure. Cyclic voltammetry demonstrated two reduction and two oxidation processes.

Summary: This study demonstrates the potential of electrochemistry hyphenated to liquid chromatography and mass spectrometry for the prediction of oxidative degradation of the antihypertensive drug valsartan in wastewater treatment plants. The researchers identified seven electrochemical transformation products of valsartan and successfully detected one of them, N-dealkylated ETP336, in wastewater treatment plant effluent. They also developed a targeted liquid chromatography-tandem mass spectrometry method for the detection of valsartan and its electrochemical transformation products, which eliminates the need for costly synthesis and isolation of reference materials. This workflow is valuable for setting up targeted analysis methods for unknown transformation products.

Summary: The capability of precisely constructing bimetallic clusters with atomic accuracy provides exciting opportunities for establishing their structure-property correlations. However, the chemistry dictating the fabrication of clusters with atomic-level control has been a long-standing challenge. In this study, the factors of steric hindrance and electronic effect of ligands, the charge state of Au-25(SR)(18), and the amount of dopant were systematically investigated. The results revealed the reversible transformation between [Au19Cd3(SR)(18)](-) and Au24Cd(SR)(18) by manipulating ligands with different steric hindrances. Additionally, a novel bimetallic cluster, Au4Cd4(SR)(12), was successfully fabricated by introducing an excess amount of dopant.

Summary: [Mn3O(OAc)(7)(HOAc)](6)·xAcOH (x=6-9) is a rare compound containing molecular Mn-18 rings. The Mn-18 rings are formed by Mn-3(mu(3)-O) subunits, in which high-spin Mn(III) centers are bridged by acetate anions (AcO-) pairs. The magnetic measurements show weak ferromagnetic interactions between the Mn-3 units within the Mn-18 rings, which can be simulated as basically uncoupled magnetic moments of each Mn-3 unit within the ring.

Summary: The nature of metal plays a key role in determining the flexibility and responsivity of isomorphous flexible metal-organic frameworks. In the case of DUT-8(M) family, different metal ions (Ni, Zn, Co, Cu) in the paddle wheel cluster result in various behaviors upon desolvation and adsorption. Ni, Co, and Zn compounds undergo a phase transition to closed pore phase and show gate opening behavior, while Cu-based compounds exhibit different flexible behavior. Desolvation of DUT-8(Cu) does not lead to the formation of closed pore phase, regardless of particle size.

Summary: Flexible porous frameworks are a cutting-edge area of materials research due to their ability to adaptively open and close pores induced by chemical and physical stimuli, offering a wide range of functions. However, the factors influencing the switchability are still poorly understood, including the role of building blocks, crystal size, defects, cooperativity, and host-guest interactions. This review discusses an integrated approach using idealized model materials to systematically investigate and understand the critical factors affecting framework dynamics, leading to progress in their understanding and application.

Summary: A unique feature of metal-organic frameworks (MOFs) is their structural switchability, which offers a wide range of functionality for sustainable energy applications. This study provides experimental evidence for fluid metastability and history-dependent states during sorption in MOFs, leading to the counterintuitive phenomenon of negative gas adsorption (NGA). The authors used various techniques to examine n-butane molecular dynamics and the framework response during the sorption process, revealing the role of metastable states in the NGA transitions.

Summary: This article investigates a new type of 0-D hybrid salt, composed of discrete organic cations and tetrachloridomanganate(II) anions. The crystal structure shows that the fused heterocyclic rings in the organic cations almost coplanar and have expected bond lengths. The tetrahedral MnCl4(2-) anion is slightly distorted with varying bond lengths and angles. In the crystal, the compound exhibits a pseudolayered arrangement with separate organic and inorganic sheets stacked alternately. The analysis also reveals the presence of non-conventional C-H center dot center dot center dot Cl-Mn hydrogen bonding in the crystal packing.

Summary: By using paramagnetic Ni2+-Co2+ pairs as spin probes, in situ continuous wave electron paramagnetic resonance investigation has been proven as a powerful method to follow the isotope-selective gate opening phenomenon on the DUT-8(Ni-0.98 Co-0.02) framework. This method is sensitive to the phase transition from closed pore to open pore phase in response to D-2 adsorption, while no phase transformation has been observed during H-2 gas adsorption. Additionally, it can sense local structural changes around the spin probe during D-2 gas desorption. Based on these evidences, the in situ continuous wave electron paramagnetic resonance method can be implemented as an efficient and non-invasive technique for the detection of dihydrogen isotopes.

Summary: This study utilizes spectroscopic techniques and density functional theory calculations to investigate the vibrational properties of DUT-8(M) materials with different metal nodes (M = Ni, Co, Zn, Cu). Experimental results show that the closed pore phase of the Ni-based compound is stiffer than those containing Co and Zn, while the open pore phase is softer. Theoretical calculations suggest that changing the metal atom mainly affects the phonon modes inducing changes in the paddle wheel unit. These findings provide valuable insights into the flexibility and phase transition mechanism of switchable MOFs.
