Summary: The molecular arrangement and orientation of tetraphenylethylene (TPE) unit in thin films and aggregates have a strong impact on the energy transfer process and luminescent behaviors. In this study, metal-TPE coordination polymer (CP) ultrathin films are self-assembled at the air-water interfaces, showing aggregate-induced emission (AIE) behaviors. The luminescence of TPEs in CPs and LB films is influenced by the coordination bonding and molecular interactions, which lead to longer emission lifetime and tunable emission wavelengths and colors. Moreover, the Cd-TPE CP LB films exhibit selective sensing to methanol and formic acid in the gas phase.

Summary: Nanoscale assembly of ultrasmall metal nanoclusters using molecular forces has been shown to be a powerful strategy to manipulate their properties in various dimensions. In this study, we demonstrate the formation of kinetically trapped assemblies with enhanced photoluminescence and extended this principle to other materials. We also show a thermal energy driven process to isolate these assemblies, which exhibit thermodynamic stability and unique properties. Our strategy may have broader applications in creating different MNC-based assemblies with unforeseen arrangements and properties.

Summary: The study involved constructing spirocyclic Ag-9 clusters by vertex-sharing of in-situ-generated heteroaryl diide-centered metal rings, demonstrating versatile photoluminescent and chiroptical behavior. Under different aggregation conditions, assembly led to cluster-based phosphorous luminescence and micrometer-long helical nanofibers. Exciton couplings of chelating ligands at molecular and microscopic levels in the assembled film of cluster enantiomers resulted in circularly polarized luminescence with a high anisotropy factor (0.16).

Summary: The anionic diamido N-heterocyclic carbene 1 is used to synthesize a variety of Cu(I) complexes with small molecular ligands. Key to the synthesis is a stable coordination polymer [1 center dot Cu](n) that can be easily converted into monomeric complexes by adding desired ligands. Spectroscopic experiments are limited to the crystalline state of the complexes, which exhibit visible luminescence in the solid state. Quantum mechanical computations reveal the role of coordination number and charge transfer character in the spectral features of the complexes.

Summary: The crystallization degree of polymer ligands determines the assembly structure of PGNPs, whether it forms diamond-shaped platelets or highly ordered three-dimensional superlattices. Moreover, the diamond-shaped platelets can continue to grow with newly added crystalline species.

Summary: Solid-state materials with piezochromic luminescence (PCL) have potential in photoelectric devices, but their practical applications are hindered by weakened luminescence in aggregation state. In this study, a highly emissive coordination polymer, CUST-805, was constructed using an AIE-active chromophore as the building block. The visible and reversible PCL of CUST-805, from blue to green, was achieved through transformation between crystalline and amorphous states. The sensor based on CUST-805 demonstrated high selectivity and sensitivity with a low detection limit of 0.29 ppm for 2,4,6-trinitrophenol.

Summary: Novel ratiometric luminescent lanthanide coordination polymer nanoparticles (CPNs) were prepared using adenosine monophosphate (AMP) and Tb3+, along with lysine (Lys) as a sensitizer, for the selective and sensitive detection of phosphate ions (Pi). The method achieved ratiometric luminescence detection by measuring the ratio between the luminescence intensities at 544 and 375 nm. The proposed assay showed strong selectivity and was successfully applied to detect Pi in real water samples.

Summary: This study explores the importance and mechanism of chiral self-assembly and self-sorting in gold cluster systems. By introducing ligands with different chirality, unique chiral gold clusters with specific shapes were successfully synthesized. Both homochiral and heterochiral self-sorting processes were observed, as well as the transfer of chirality from ligands to gold clusters, resulting in changes in symmetry.

Summary: Metal ions play a key role in modulating the aggregation of amyloid-beta peptide (Aβ) in Alzheimer's disease (AD). Recent studies have provided detailed insights into the molecular structures and dynamics of metal-bound Aβ complexes and the effect of metal ions on the Aβ aggregation process. The interaction between metal ions and Aβ reduces the fibril-end elongation, leading to an increased formation of Aβ oligomers, which contributes to the understanding of metal-Aβ-associated neurotoxic effects.

Summary: In this study, a pair of chiral copper(I) cluster-assembled materials (R/S-2) was prepared and exhibited unique photo-response characteristics in DMSO solution. By combining R/S-2 with a PMMA matrix, the first photo-activated CPL film was developed, which showed a reversible photo-response and excellent fatigue resistance. The study revealed that the photo-response properties are attributed to the AIE characteristics of R/S-2 and a photo-induced deoxygenation process. This study enriches the types of luminescent cluster-assembled molecules and provides a new strategy for metal cluster-based stimuli-responsive composite materials.

Summary: Self-assembly relies on the ability of smaller entities to arrange into organized systems, with the design of the media playing a crucial role. The media determines the self-assembly pathway and can control the wrapping process of supramolecular homo-aggregates by a different crystal lattice component. This reverse coating process is controlled by the media composition and could lead to the construction of hierarchical supramolecular structures.

Summary: Silver(I) coordination compounds exhibit diverse geometries, different coordination numbers, and the ability to form argentophilic interactions. Subtle modifications in thiolate and phosphine ligands have significant effects on the nuclearity and geometry of phosphine capped clusters, with insights gained through analysis of electronic density and interaction energy. This control of ancillary ligands is important for the precise construction of higher nuclearity clusters.

Summary: The use of self-assembly is a popular topic in supramolecular chemistry for constructing complex functional structures. Biomolecule-based building blocks have been employed to develop intracellular assemblies, with a focus on their potential biomedical applications. In contrast, the use of inorganic building blocks is still in its early stages and encounters challenges in constructing in-bio self-assemblies. Nonetheless, the potential advantages of inorganic self-assembly in living cells are expected to drive new discoveries in this field.
