Summary: A series of halogen-bonded discrete, one-dimensional supramolecular architectures were prepared by co-crystalizing a sterically hindered class of homologous ditopic para-xylenes with mono-, di-, and triiodofluorobenzene. The solid-state structures investigated by X-ray diffraction show that the molecular geometry of the tectons and halogen bond directionality translates into corresponding XB cocrystals with a conformational twist at the planes of para-xylene. The bipyridine tectons grafted with photo-responsive azobenzene side-group can be remotely modulated by light in the halogen-bonded chains, offering innovative applications possibilities.

Summary: This study reports a facile bottom-up solution fabrication process to obtain metal-free supramolecular glasses (SMGs) at the macroscopic scale using L-Histidine and hexamethylenetetramine as building blocks. The chiral SMGs possess color-tunable ultralong room temperature phosphorescence (decay lifetime up to 141.2 ms) and circular polarized luminescence (g factor up to 8.7x10(-3)). The strong hydrogen bonds effectively drive the formation of SMGs, and provide a rigid microenvironment to boost triplet exciton generation. Applications including multicolored displays, visual UV detection, and persistently luminescent thermometer are demonstrated based on the excitation- and temperature-dependent ultralong phosphorescence of the SMGs.

Summary: The research shows that size is a common structural driving force for controlling hierarchical assembly of inorganic nanoparticles into anisotropic superstructures. The increase in size creates an effective kinetic barrier at different attachment sites, switching the assembly pathway from thermodynamically preferred 3D to kinetically favored 1D. Furthermore, the size-encoded hierarchical assembly is accompanied by ligand-controlled Oswald ripening process, resulting in the variation of hierarchical patterns from chains to tubules.

Summary: The impact of phenyl ring and molecular stiffness on self-assembly phenomena in aromatic alcohols was studied using a combination of dielectric, infrared, and diffraction studies. It was found that increased steric hindrance and intramolecular stiffness lead to decreased size and order of nanosized clusters. Furthermore, a twofold intermolecular assembly was proven to exist in aromatic alcohols via O-H···π and O-H···O schemes.

Summary: Au-pseudocarbynes are a new class of materials formed through non-covalent interactions between one dimensional sp-hybridized carbon chains and sub-nanometer metal clusters. These materials exhibit theoretical strength, elastic modulus, and stiffness comparable to carbyne. The synthesis of Au-pseudocarbynes typically relies on laser ablation, but this study demonstrates an alternative method using self-assembly of gold clusters and polyynes in solution, which yields similar results to laser ablation synthesis. This self-assembly approach provides new insights into the formation mechanism and enables large-scale synthesis for potential applications.

Summary: In this work, a strategy of directly using the hydrogen-bonded organic framework (HOF) monomer for efficient photoredox catalysis without catalyst prefabrication is reported. This simplified mode showed equal effectiveness as the prefabricated HOF catalysts, with high activity, selectivity, and generality in photocatalytic sulfide oxygenation. The in situ self-assembly of the HOF monomer into the target HOF framework was achieved through complementary hydrogen bonds of carboxy dimers. The enhanced yield of singlet oxygen (1O2) resulting from the excitonic effect and strong interlayer confinement of self-assembly frameworks explained the origin of activity. This work offers a facile yet efficient approach to utilize HOF material for photoredox catalysis.

Summary: We present a room temperature STM study on the dynamics of a quasi-liquid perylene monolayer formed on Ag(110) under thermal equilibrium. The thermodynamic balance of molecule-molecule and molecule-substrate interactions generates a compact 2D quasi-liquid state with three distinct motion modes. The substrate lattice guides and provides distinct registers for each mode, preventing segregation and maintaining memory in the intermingled molecules. Fourier transform analysis reveals long-range spatial correlations and an epitaxial character of the quasi-liquid state, while short-range mode coupling analysis helps understand the mechanism of long-range mode coupling. The substrate force field induces a dynamical ergodic-non-ergodic phase transition, resulting in a stationary long-range ordered quasi-liquid state ((-1)(25)(3)(2)).

Summary: The coupling of a sterically demanded pentacene derivative on Au(111) into fused dimers connected by non-benzenoid rings was studied using high-resolution scanning tunneling microscopy/spectroscopy and density functional theory. The diradical character of the products was tuned by modifying the coupling section, with the antiaromaticity of cyclobutadiene and its position within the structure playing a significant role. Understanding these structure-property relationships is crucial for designing new complex and functional molecular structures.

Summary: We report the ultrasensitive and anti-interference detection of SARS-CoV2 spike protein in untreated saliva using an antibody/aptamer-free (AAF) SERS substrate, applying the evanescent field induced by the high-order waveguide modes of well-defined nanorods for SERS for the first time. A detection limit of 3.6 x 10-17 M and 1.6 x 10-16 M are achieved in phosphate buffered saline and untreated saliva, respectively, which are three orders of magnitude better than the best records from AAF substrates. This work unlocks an exciting path for designing AAF SERS substrates for ultrasensitive biosensing, not limited to the detection of viral antigens.

Summary: In this study, we report the large-distance confinement of electronic states in a single-layer graphene (SLG) by an extended molecular adlayer. Despite being 6.7A away from Cu(111) with the graphene sheet in between, the defined corrals can still effectively trap the free electron gas of the Cu surface, lifting the dispersive band of Cu. The migrated electrons from the Cu substrate to SLG are shown to accumulate above the SLG surface instead of at the Cu-SLG interface. The physisorbed molecular layer sharpens the dispersion of graphene electronic states. These results open up new possibilities for the design of hybrid electronic devices and graphene modification.

Summary: By decorating small Cu2S nanocrystals uniformly on Cu nanosheets, this electrocatalyst integrates three desirable features, including a high positive local charge on Cu (Cu delta+), abundant interfaces between Cu delta+ and zero-valence Cu0, and a non-flat, stepped catalyst surface. This promotes the affinity of *CO, decreases *COCO formation barrier, and thermodynamically prefers *CH2CHO-to-*CH3CHO conversion. As a result, a high partial current density of about 20.7 mA cm-2 and a Faraday efficiency of 46% for C2H5OH are achieved at -1.2 V vs reversible hydrogen electrode in an H-cell containing a 0.1 M KHCO3 solution. This study proposes an efficient strategy for high-yield CO2-to-C2H5OH conversion, highlighting the potential for industrial production of alcohol and related products from CO2.

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.
