Summary: This study reports highly efficient green-emitting PeLEDs by introducing semiconducting molecular additives (Fl-OEGA and Fl-C8A). The conjugated additives exist primarily at the grain boundaries of perovskite, reducing the contact potential difference and residual tensile stress. The PeLEDs with Fl-OEGA show minimal shift in turn-on voltage and less decrease in current density compared to devices with insulating EDEA. Furthermore, the 3D CsPbBr3-PeLEDs achieve the highest external quantum efficiency of 21.3% with the incorporation of semiconducting Fl-OEGA as a new multifunctional additive.

Summary: This study proposes the rational design of a dual S-scheme heterojunction in lychee-shaped W18O49/CdWO4/CdS nanostructures to achieve high photocatalytic activity in hydrogen evolution reaction (HER) under visible light irradiation. The significant activity of W18O49/CdWO4/CdS in photocatalytic HER is attributed to its unique structure, effective charge separation by the photoinduced defect-transit dual S-scheme mechanism, and strong internal electric field. X-ray photoelectron spectroscopy (XPS), femtosecond transient absorption (fs-TA) spectroscopy, and electron paramagnetic resonance (EPR) measurements further confirm the dual S-scheme mechanism in the photoinduced carrier transfer pathways. This research provides a new strategy for designing dual S-scheme heterojunctions to improve photocatalytic performance through defect band structure engineering.

We grew ultrathin MoS2 nanocrystals with specific features using salt-assisted chemical vapor deposition.

Summary: This study proposes the design of a linear conjugated polymer by creating a chain polymer connected via bridging covalent bonds in one direction and retaining pi-stacked aromatic columns in its orthogonal direction. Three analogs of linear conjugated polymers with different aromatic cores and bridging groups are prepared. The Oxamide-PDI (perylene diimide) exhibits high crystallinity, wide light absorption, and increased stability, resulting in a remarkable oxygen evolution rate of 5110.25 mu mol g(-1) h(-1) without any cocatalyst. The built-in electric field in Oxamide-PDI enables efficient charge carrier migration and separation.

Summary: The coexistence of single-crystallinity with a multidomain morphology is a paradoxical crystallographic phenomenon. The authors demonstrate the formation of metallo-organic single-crystals with a unique appearance, formed from unstable, monodomain crystals. Despite different morphologies and growth mechanisms, the crystallographic structures of mono- and multidomain crystals are nearly identical. Sonication of solvents generating radical species is essential for forming the multidomain single-crystals, offering opportunities to generate a new class of crystals.

Summary: Earth-abundant metals have become increasingly important in homogeneous catalysis, particularly in the hydroboration reactions of challenging substrates like nitriles, carbonates, and esters. The use of manganese(II) triflate salt in combination with potassium tert-butoxide and pinacolborane enables efficient hydroboration of these substrates with near quantitative yields in less than three hours at room temperature, showcasing a simple and effective methodology for these transformations. Further studies indicate that other earth-abundant metal triflate salts can also facilitate this reaction, expanding the scope of this catalytic process.

Summary: We demonstrate that the optical properties of indigo carmine can be controlled by encapsulating it within a coordination cage. Depending on the ratio of the host/guest molecules, the cage can selectively encapsulate one or two dye molecules. The 1:1 complex exhibits fluorescence, which is unique for an indigo dye in an aqueous solution. Furthermore, we have discovered that binding two dye molecules stabilizes a previously unknown conformation of the cage.

Summary: Metal-organic frameworks based on tetrahedral pyridyl ligands can form a series of isostructural crystals with different metal ions and properties. By conducting cation exchanges, an iterative crystal-to-crystal conversion can be achieved, which is influenced by the stability of the resulting coordination nodes. The optical and magnetic properties of the crystals are controlled by the metal cation, and the crystals preserve their morphology, enabling quantitative comparison of their properties at both the ensemble and single-crystal level.

Summary: Modulating the packing modes of bio-inspired supramolecular assemblies can significantly enhance the electromechanical properties of the assembly architectures. This study introduces a co-assembly strategy to achieve this by changing the amino acid chirality and mixing with a nonchiral bipyridine derivative. The resulting centrosymmetric-crystallizing coformer increases the single-crystal piezoelectric response of the electrically active bio-inspired molecular assembly.

Summary: In this study, the researchers engineered the precise positioning and alignment of arrays of two different guest molecules in a crystalline host matrix, resulting in new optically active materials. They found that sub-nm differences in the diameters of two types of 1D channels were enough for selective inclusion of dyes. Energy transport occurred between parallel-positioned nanochannels of different dyes through Forster resonance energy transfer (FRET). The color of individual micro-sized crystals depended on their relative position under polarized light, which was influenced by the crystallographic packing of the host matrix and the concentration of the dyes.

Summary: The symmetry of a crystal's morphology is usually related to the crystallographic packing's symmetry. Convex polyhedrons are commonly used to describe the morphology of single crystals. However, concave polyhedrons are indicative of twinning and polycrystallinity, and are not usually associated with single crystal structures. In this study, we report a new type of structure: a concave polyhedron shape single crystal with a multidomain appearance and a rare space group (P622). Despite its unusual structural features, the hexagonal symmetry is still evident at the morphological level.
