Summary: Porous aromatic frameworks (PAFs) are versatile porous materials with promising functionality, but the synthesis of PAFs with desired properties is challenging. In this study, a multivariate inspired strategy was employed to successfully synthesize PAFs with highly porous and hierarchical structures. The PAFs obtained through this strategy exhibited both hierarchical structures and high specific surface areas. Furthermore, lipase was loaded onto one of the multivariate PAFs, showing high loading content and favorable catalytic activity and stability.

Summary: Zeolitic imidazolate framework-8 was synthesized in a containerless state using acoustic levitation, which affected the coordination connection of ligands and resulted in different particle size distribution compared to normal conditions. The influence of droplet evaporation during acoustic levitation synthesis was investigated using methanol as the solvent. Surface evaporation caused deformation, vibration, and shape oscillation of the droplets, leading to a decrease in particle size distribution.

Summary: Step-shaped adsorption-desorption of gaseous payloads by flexible metal-organic frameworks can facilitate the delivery of large usable capacities with reduced energetic penalties. The multivariate linker approach is a powerful tool for tuning the phase change behavior of flexible frameworks. In this work, a multivariate framework was developed with a considerably reduced threshold pressure and desirable adsorption-desorption profile for efficient storage and delivery of weakly physisorbing species.

Summary: Based on stable Zr6O4(OH)4 metal clusters, UiO-67 was used for U(VI) adsorption and compared with UiO-66. It was found that UiO-67 had a larger surface area and pore volume than UiO-66, leading to 1.68 times higher adsorption capacity for uranium. However, the chemical stability of UiO-67 decreased with the extension of organic ligands. The carboxyl groups in UiO-67 were found to participate in the chemisorption of U(VI).

Summary: The luminescence properties of two series of lanthanide-containing metal-organic frameworks were studied, showing characteristic emissions of Nd(III), Eu(III), and Tb(III) in different compounds. The color of emission in mixed-lanthanide complexes can be fine-tuned depending on the relative amount of Eu(III) and Tb(III). A small amount of Eu(III) is sufficient for observing the most intense Eu(III) transitions.

Summary: By utilizing solvent-oriented structural self-assembly and solvent-induced single-crystal to single-crystal transformation strategies, eight structurally distinct Cd-CPs were controllably synthesized with the same linkers for the first time. The significant role of solvents in the self-assembly and transformations in CPs has been demonstrated, and rare reversible CP-based phase transition phenomena at low temperatures were observed, including the first example of a novel turn-on-off CP-based Fe3+ ion sensor.

Summary: Tetradymite-type Bi2Te3 is synthesized via a solid-state method and its electrochemical phase evolution upon discharge against Li, Na, and K counter-electrodes is detailed. Rietveld analysis reveals that Li and K systems undergo a sequence of intercalation, conversion, and alloying reactions. Bi2Te3 shows high initial capacities for Li, Na, and K cells, but poor cyclabilities due to large volume changes and irreversibilities. Gravimetric capacities for Li, Na, and K half-cells decrease significantly after several cycles.

Summary: A series of Cu2-xMxCd compounds were prepared by high temperature solid state synthesis, and it was found that the valence electron concentration (VEC) correlated with phase stability. The incorporation of M (Zn, Ga, Ge, Sn) led to the formation of gamma-brass type and MgCu2 type Laves phases. The cubic Laves phases were stable within a narrow homogeneity range, whereas at higher M content, the stable pseudo-binary cubic phase transformed into binary compounds. First principles density functional theory calculations were used to explain the stability and bonding characteristics of the pseudo-binary Laves phases.
