Summary: In this study, the mechanism of assembly of nanocubes grafted with short-chain molecules was computationally investigated. It was found that the assembly pathway of nanocubes is very rugged involving multiple energy barriers and metastable states. The assembly mechanism is dominated by sliding motion of nanocubes relative to each other punctuated by their local dissociation at grafting points involving lineal separation and rolling motions.

Summary: In this study, 2D CsPbBr3 nanosheets with a thickness of about 3 nm were successfully synthesized, and their lateral dimensions were found to be adjustable by tuning the ratio of short and long ligands. The nanosheets resulted from the self-assembly of CsPbBr3 nanocubes, with a narrow amorphous region between adjacent nanocubes. Insights into the structure and growth mechanism of these nanosheets were obtained through microstructural characterizations and theoretical calculations.

Summary: This study presents the construction of artificial homohelical assemblies by blending inorganic polyoxometalates (POMs) and organic cyclodextrin molecules. The chiral double-helical chains were achieved through a left-hand arrangement, and the process of assembly showed chiral transfer and amplification from molecule to superstructure. The capability of the homohelical aggregate for enantioselective adsorption was demonstrated, enriching the design of POM-based inorganic-organic materials.

Summary: By designing and fabricating a novel nanoscaled polyoxometalate-based humidity-responsive molecular actuator {Bi8Mo48}, actuation at the molecular level is achieved and the mechanism is elucidated. {Bi8Mo48} exhibits a semi-flexible cage-like architecture with oxygen-rich surfaces and highly negative charges 72-. The nanoscaled molecular actuator shows reversible expansion and contraction behavior under humidity variations due to lattice expansion and contraction induced by hydrogen bonding and solvation interactions between {Bi8Mo48} and water molecules. Molecular dynamics simulation further provides a fundamental understanding for the mechanism of humidity actuation at the molecular level.

Summary: The assembly of colloidal particles into superstructures is significant for understanding collective behavior and designing novel colloidal materials. Light plays a crucial role in the directed assembly process, and the understanding of light-matter interaction is critical for tailoring assembly kinetics. Colloidal atoms exhibit diversity in size, shape, and composition, enriching the geometric complexity of colloidal matter. The emerging applications of colloidal superstructures in nanophotonics, nanocatalysis, and nanomedicine are discussed.

Summary: Trapping surface-functionalized faceted nanoparticles at fluid-fluid interfaces can control particle orientation and facilitate their assembly into unique one- and two-dimensional superstructures. By tuning the graft density and differences in miscibility, nanocubes can be induced into different orientations. These orientationally constrained nanocubes can assemble into various unusual structures, which have potential applications in plasmonics, optics, catalysis, and membranes.

Summary: An orthogonal, noncovalent approach is presented for the assembly of higher-order DNA origami nanostructures. By incorporating perfluorinated tags into DNA origami tiles, their hierarchical assembly is controlled via fluorous-directed recognition. This integrated catch-and-latch approach combining fluorous effect with base-pairing specificity enables increased assembly efficiency and requires fewer DNA sequences, providing a cheap and efficient means for producing discrete superstructures in DNA nanotechnology.

Summary: Binary high temperature Al3Mn (T-phase) and its extensions in ternary systems have been extensively studied in crystallography. The presence of a center of symmetry in these structures has been a topic of debate. Our research on the Al-Mn-Pt T-phase demonstrates that within a continuous homogeneity region, the Al-rich T-phase belongs to the non-centrosymmetric space group Pna2(1), while the Al-poor T-phase is centrosymmetric, specifically Pnam. This change in symmetry is explained based on metallurgical and crystallographic considerations.

Summary: The pressure-induced phase transitions of (MAgF3)-Ag-I-F-II perovskites have been theoretically predicted for the first time up to pressures of 100 GPa. Different from CsAgF3 which undergoes a single phase transition, the transitions for M=K and Rb involve a sequence of transformations from orthorhombic to monoclinic and back to orthorhombic, associated with bending and approaching of infinite chains of [AgF6](4-) octahedra.

Summary: A new series of heterometallic wheels were synthesized and characterized. These wheels consist of trinuclear mu(3)-oxo-linked or hexanuclear mu-OH-linked Fe(III) pivalate clusters and rare earth nitrates. The magnetic studies revealed antiferromagnetic exchange interactions within the Fe-3 trimeric unit, as well as ferromagnetic exchange interactions between the Fe(III) and Ln(III) centers when diamagnetic Y(III) is substituted by paramagnetic Ln(III).

Summary: Phosphate ester bonds are stable in nature and can be isolated using a combination of phosphoryl and calix[4]arene moieties. In this study, hydrolyzed phosphoryl-calix[4]arene ligands were formed through Ln(III)-mediated P-OEt bond cleavage in L-PO. The resulting Ln(III) species were trapped as dimers, and the Dy derivative exhibited slow magnetization relaxation. This strategy can be further applied to create a broader range of hydrolyzed platforms that mimic nuclease enzymes.

Summary: We demonstrate a concept of molecular-level spintronics by studying spin centers antiferromagnetically (AFM) coupled to result in a singlet ground state. By performing time-dependent quantum transport measurements, we observe distinct current transitions corresponding to the AFM states of individual molecular complexes grafted on a carbon nanotube. Our statistical analysis shows independent switching events for cobalt complexes and coherent superposition of AFM spin states for manganese complexes.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
