Summary: The hierarchical self-assembly process has great potential for constructing nanostructural superlattices, but precise regulation remains a challenge. This study introduces the concept of unimolecular nanoparticles (UMNPs) that act as supramolecular motifs and directly assemble into superlattices. The discovery of complex phases and support for the previously proposed self-sorting process are provided by blending UMNP with conventional giant molecules.

Summary: A multifunctional self-assembled AuNPs array (MSANA)-based LDI-MS platform was developed for direct amino acids analysis and metabolic profiling in patient CSF samples. The platform demonstrated high selectivity and micromolar sensitivity for capturing and analyzing aromatic amino acids. It also exhibited excellent reproducibility (RSD < 10%) compared to the widely used direct matrix spotting approach (RSD < 44%). The platform was successfully used for metabolic profiling of CSF, enabling the discrimination of medulloblastoma patients from non-tumor controls within minutes. Overall, the MSANA-based LDI-MS platform shows potential clinical values for large-scale metabolic diagnostics and pathogenic mechanism study.

Summary: This study reports a simple method of creating a solvent flow by contacting a sample solution droplet with tissue paper, which generates capillary force. The dynamics and solvent removal during this process promote the formation of a stable linear quasi-crystal composed of specific molecules, which would otherwise form random tiling. Compared with the random tiling case, the tailored quasi-crystal template allows for a higher-efficiency accommodation of fullerene molecules.

Summary: Porosity and surface area analysis are important in modern materials science. However, there is a lack of attention to the reproducibility issue in calculating BET surface areas from identical isotherms, raising concerns over the reliability of reported BET areas. To address this, a new computational approach called BET surface identification (BETSI) has been developed for accurately and systematically determining the BET area of nanoporous materials.

Summary: We are witnessing the dawn of hydrogen economy, where hydrogen is becoming a primary fuel for heating, transportation, and energy storage. Metal-organic frameworks (MOFs) have emerged as promising adsorbent materials for hydrogen storage, but their use has been limited by a lack of densification methods. In this study, researchers screened and analyzed a database of MOFs to find an optimal material for hydrogen storage, and successfully synthesized and evaluated a monolithic MOF with high storage performance at lower operating pressures.

Summary: We report on the formulation of all-inorganic perovskite nanocrystals inks and their application in graphene photodetectors. By controlling the device structure and fabricating process, we achieved high photoresponsivity and controlled spectral response. Inkjet printing of perovskite, graphene, and gold nanoparticle inks enabled the realization of fully printed photodetectors with the highest reported photoresponsivity value. The developed perovskite ink offers opportunities for stable and sensitive graphene-based photon detectors.

Summary: Designing hydrogen-bonded organic frameworks (HOFs) with low densities and high porosities is challenging due to the preference for close packing in most molecules. Crystal structure prediction (CSP) can rank alternative crystal packings for organic molecules based on their lattice energies. By combining CSP with structure-property predictions, a previously unknown low-energy HOF (TH5-A) with remarkably low density and three-dimensional pores was discovered for triptycene trisquinoxalinedione (TH5). This TH5-A polymorph demonstrates high porosity with a surface area of 3,284 m(2) g(-1), making it one of the most porous HOFs reported.

Summary: We investigated the photochemical and chemical processes of Mn(diimine)(CO)(3)X (X = halide) complexes in permanently porous metal-organic frameworks (MOFs). We observed the photo-liberation of CO from the metal and its escape from the MOF crystals. Crystallographic snapshots of the photolysis products were obtained due to the high crystallinity and structural flexibility of the MOF. Time resolved experiments revealed complementary spectroscopic studies and characterized the final photolysis product as a possible Mn(ii) entity. These findings provide insights into the chemistry of MOF-based photoCORMs and catalysts.

Summary: Non-thermal plasma (NTP) is a promising state of matter for chemical reactions, providing high densities of reactive species without the need for a catalyst at atmospheric pressure and moderate temperature. However, a better understanding of the complex interactions between NTP and liquids is needed for comprehensive use of NTP in reactions. This study details the construction of a microfluidic reactor and a corresponding batch setup for NTP chemical reactions in organic solvents, enabling controlled generation of NTP and inline data collection. The developed frameworks contribute to the potential applications of NTP in chemical synthesis.

Summary: This study investigates the synthesis of Mn-based metal-organic frameworks (MOFs), finding that MnMOF-1 is a kinetic or metastable phase, while a newly identified 2D layered material, MnMOF-2D, is the thermodynamically favored product. It is also shown that using longer linkers can help to form more stable structures. In addition, two new porous 3D Mn-based MOFs were successfully synthesized, highlighting the viability of using tetratopic hinged linkers to form 3D MOFs.

Summary: A thermally induced order-disorder transition of 2H-TPP on Au(111) was investigated using scanning probe microscopy and X-ray photoelectron spectroscopy. The transition from an ordered close-packed phase to a disordered diffuse phase was found to be correlated with an on-surface cyclodehydrogenation reaction, and further heating of the diffuse phase resulted in the formation of a distinct nitrogen environment indicative of the Au-TPP species.

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.
