Summary: In this study, a pair of chiral two-dimensional lead bromide perovskites R-/S-(C3H7NF3)(2)PbBr4 (1R/2S) was synthesized using a H/F substitution strategy, which exhibit circular dichroism (CD) and circularly polarized luminescence (CPL) activity. Compared with one-dimensional non-centrosymmetric (C3H10N)(3)PbBr5 with local asymmetry obtained by isopropylamine, 1R/2S show a centrosymmetric inorganic layer despite the global chiral space group. Density functional theory calculations show that the formation energy of 1R/2S is lower than that of (C3H10N)(3)PbBr5, which implies the improved moisture stability in photophysical properties and CPL activity.

Summary: Zero-dimensional organic-inorganic metal halide hybrids have been studied to explore pressure engineering of electron-phonon coupling and self-trapped exciton emission at the molecular level. However, the low stiffness of inorganic clusters limits their reversible tuning of physical properties. In this study, a Sb3+-doped metal halide with high emission yield and bulk modulus was designed, allowing for reversible and enhanced self-trapped exciton emission under pressure. These findings provide insights into the structure-property relationship and molecular engineering of zero-dimensional metal halides for wide-band and pressure-sensitive light sources.

Summary: This study reports the interesting and unique cation-exchange behaviors of the first indium-bridged purely inorganic 3D framework based on high-nuclearity polyoxoniobates as building units. The material features a near-icosahedral core-shell structure with changeable openings for binding different metal cations via ion-exchanges and exhibits unusual selective metal-uptake behaviors. Single-crystal-to-single-crystal metal-exchange processes can produce a dozen new crystals with high crystallinity, allowing for the detailed visualization of metal-exchange interactions and mechanisms at the atomic precision level. This work is of significance for the exploration of cluster-based ion-exchange materials that are still to be developed.

Summary: This study systematically investigated the hydrogenation of methyl palmitate (MP) to hexadecanol over defect-rich Cu/m-ZrO2 catalysts. It was found that Cu/m-ZrO2-350 catalyst exhibited the best activity for MP hydrogenation due to its highest Cu dispersion, largest number of Cu0 sites, and surface oxygen vacancy concentration. The synergistic effect of Cu species and oxygen vacancies provides insights for the design of efficient catalysts for the conversion of fatty esters to fatty alcohols.

Summary: An oxalate-assisted strategy was developed to create new polyoxotantalates (POTas). Two brand-new POTa supramolecular frameworks based on uncommon dimeric POTa secondary building units (SBUs) were constructed and characterized using this strategy. The oxalate ligand served as both a coordination ligand to form unique POTa SBUs and a key hydrogen bond acceptor to construct supramolecular architectures. These architectures exhibited outstanding proton conductivity. This strategy opens up new possibilities for the development of POTa materials.
