Summary: A double-walled tetrahedral metal-organic cage was assembled in solution using silver(I), 2-formyl-1,8-naphthyridine, halide, and a threefold-symmetric triamine. The cage has an inner set of tetrahedron walls that are surrounded by the outer four, with significant interior volume for binding anionic guests. External binding clefts located at the edges of the cage can bind small aromatic guests. The exchange of halide ions on the silver clusters allows for modulation of the cavity volume, enabling targeted binding behavior.

Summary: In this study, a new hierarchical assembly strategy is proposed for the rational and precise construction of complex single-crystal superstructures. Unprecedented superclusters in Rubik's cube form are formed by aggregating oxohalide clusters as secondary building units. These Rubik's cubes then act as isolable tertiary building units to assemble diverse single-crystal superstructures. The captured intermediate assembly states provide a profound understanding of the assembly process at the atomic level.

Summary: By decorating nanographenes with alkyl chains and controlling concentration, solvent polarity, temperature, and sonication, it is possible to achieve self-assembly and formation of stacked structures. Optical measurements and AFM images confirm the presence of stacked structures, while molecular mechanics calculations model the interactions within the aggregates. The nanographenes exhibit concentration-dependent morphologies, forming stacked structures at low concentrations and polymer-like network structures at higher concentrations on mica.

Summary: An efficient strategy to enhance charge transport in pillar[5]arene self-assembled monolayers (SAMs) by introducing cationic guests is reported. The current density of pillar[5]arene SAMs can be significantly increased by inserting cationic molecules into the cavity of pillar[5]arenes. Furthermore, a positive correlation between the charge transport and binding affinities of pillar[5]arene-based complexation is observed. The enhancement of charge transport is attributed to the efficient host-guest interactions that stabilize the supramolecular complexes and lower the energy gaps for charge transport.

Summary: The pursuit of good photophysical properties in organic optoelectronic materials necessitates an understanding and control of chromophore interactions, particularly in their aggregating form. This study presents a customizable molecular design using dissymmetrical ligands to precisely control chromophore interactions through the formation of metal-organic dimers. Anti-paralleled stacking of dissymmetrical ligands in these dimers allows for lateral shifting of chromophore stacking, with the spacing determined and adjusted by ligand dissymmetry. Three metal-organic dimers with varying chromophore spacing exhibited unique photophysical properties and displayed high-efficiency luminescence against quenching. This strategy offers a universally applicable approach to construct chromophore dimers with fixed cofacial spacing and determinate through-space interactions.

Summary: Charge transport through peptides can mimic complex protein processes, allowing for the development of high-performance bioelectronic devices and the understanding of biomolecular recognition and information transfer mechanisms. Modulating charge transport through individual peptides has been achieved, but intermolecular modulation remains challenging. To address this challenge, we used self-assembled monolayers (SAMs) of oligopeptides as models and explored an interfacial amino acid strategy for charge transport modulation. Our results showed that non-covalently interfaced, charged amino acids effectively attenuated charge transport. Analysis revealed that the attenuation was due to decreased molecule-electrodes coupling and reduced polarizability. This efficient strategy advances our understanding of charge transport in biological systems and facilitates the development of future electronics.

Summary: Understanding the charge migration across peptide chains is crucial for both biology and biomolecular electronics. This study investigated the relation between charge migration in wet electrochemistry and on the solid state by studying ferrocene-labeled peptide self-assembled monolayers on Au substrates. The results showed that the ability of peptides to transmit charge was more influenced by peptide length on the solid state compared to wet electrochemistry. Additionally, altering peptide compositions had different consequences for charge migration in wet electrochemistry and on the solid state.

Summary: In this study, two trigonal prisms (SA and SB) based on the 1,3,5-triazine motif were prepared and distinguished by hydrophobic groups. They showed high luminescence efficiencies, overcoming the fluorescence quenching caused by ir-ir interactions. SB with alkyl chains exhibited weak fluorescence in solution but enhanced intensity in the aggregated state, while SA's PLQY gradually decreased with aggregation. The self-assembly of SB formed nanorods due to hydrophobic interactions, while SA aggregated into spheres under the influence of ir-ir interactions.

This study presents a new strategy for convenient and precise self-assemblies of 3D supramolecular structures by introducing self-coordination ligands. Two meta-modified terpyridyl ligands were designed and synthesized, and their capability to assemble into hourglass-shaped nanocages was demonstrated. The assembly mechanisms and hierarchical self-assemblies of these structures were investigated, and it was shown that various higher-order assembly structures can be achieved by tuning the environmental conditions.

Summary: The study investigates the electrochemiluminescence (ECL) properties of tetraphenylethylene-based supramolecular architectures. The strong ECL emission is attributed to factors such as restricted rotation of the benzene ring, intramolecular charge transfer (ICT), and electrostatic interactions. The best-performing system shows a high ECL cathodic efficiency exceeding that of the benchmark compound in aqueous solution by nearly six-fold. This study provides insights into the programmable synthesis of high-performance aggregation-induced electrochemiluminescence emitters.

Summary: Luminescent metal-radicals have gained attention for their potential applications in materials science. However, the luminescence of metal-radicals tends to decrease after forming metallo-complexes. This study presents a highly luminescent metallo-supramolecular radical cage (LMRC) constructed from a tritopic terpyridinyl ligand RL with a TTM radical and Zn2+. LMRC shows a remarkable photoluminescence quantum yield and high photostability. Additionally, LMRC exhibits significant magnetoluminescence at high concentrations, indicating negligible spin-spin interactions between radical centers.

Summary: Drug-induced liver injury (DILI) is a common cause of acute liver failure in the USA and Europe, but most cases can be recovered or prevented by discontinuing the offending drug. Recent research has found that peroxynitrite (ONOO-) can be used as a potential indicator for early diagnosis of DILI, and there is an urgent need to establish a method to detect and track peroxynitrite in DILI cases. In this study, a FRET-based nano fluorescent probe CD-N-I was developed, which showed high selectivity and sensitivity in detecting peroxynitrite. The probe successfully detected exogenous peroxynitrite in live cells and endogenous peroxynitrite in APAP-induced liver injury of HepG2 cells.
