Summary: The researchers reported that a non-planar saddle-shaped N-heterocycle-fused metallo-porphyrinoid can directly form a persistent microporous crystalline material from solution, which can undergo solvent exchange without loss of microporosity. The material is formed by a unique accumulation of intermolecular interactions involving pi-pi stacking of the fused heterocycle, coordinative interactions at the metalloporphyrinoid unit, and hydrogen bonding. This intermolecular multipoint interaction concept will be key in the future molecular design for on-demand synthesis of porous materials, and the simple implementation of the compound described here indicates the excellent potential for device materials' synthesis. Sensing properties of the material incorporated into a nanomechanical sensor array are also reported.

Summary: We investigated the influence of the degree of phenol substitution on the molecular interactions and structural properties of self-healing hydrogels. Our results revealed that an increase in the degree of phenol substitution enhanced the interactions between chitosan-phenol and DB-PEO, leading to stronger dynamic covalent bond cross-linking. However, excessive phenol groups reduced the binding between chitosan-phenol and DB-PEO when the degree of phenol substitution exceeded 15%.

Summary: The conformation and alignment of molecules in organic materials are important for their bulk physical properties. In this study, the conformation and alignment of a donor-acceptor-type molecule, IBN, are investigated in both 2D and 3D assemblies using STM and X-ray crystallography. The results show that IBN has a planar conformation in both assemblies and the dipole moment is cancelled out by molecular alignment. The orientation and self-assembled structure of IBN in 2D assemblies are affected by the surface density of IBN and the crystal orientation of Au(111).

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions.
