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: This study introduces a new enantiomeric pair of superatomic silver clusters, R/S-Ag-17, prepared from chiral alkynyl ligands, which exhibit near-infrared emission and circularly polarized luminescence. Experimental and theoretical evidence suggest that the CPL originates from transitions between superatomic 1P(z) and 1S orbitals. This work paves the way for the development of CPL-active metal nanoclusters utilizing chiral ligands and demonstrates the transfer of chirality from protecting ligands to superatomic states in metal clusters.

Summary: In this study, we found that the circularly polarized photoluminescence (CPL) of self-assembled conducting polyaniline (PANI) helical microfibers can be reversibly switched by applying an alternating electrical bias. The conducting polymer transfers its chirality to the coassembled aggregation-induced emission (AIE) fluorescent molecules, resulting in electrochemically switchable CPL. This is derived from the reversible transformation of the chirality of the polyaniline microfibers, possibly due to the change in the molecular interchain distance upon doping/dedoping. Double-layer information encryption based on the electrochemically reversible CPL and conductance has also been demonstrated.

Summary: This work demonstrates the development of high performance fluoropolymers through a living polymerization mechanism. The synthesized poly(trifluoromethyl methylene) exhibits excellent properties such as resistance to chemical corrosion, high hydrophobicity, and low dielectric loss. The polymer can form stable helices and shows high optical activity and circularly polarized luminescence when synthesized using chiral palladium catalysts. Moreover, the polymer can be completely degraded to (E)-1,1,1,4,4,4-hexafluorobut-2-ene at high temperatures (>280 degrees C) and can be further modified.

Summary: In this study, circularly polarized phosphorescent materials were successfully constructed using water-soluble, pseudo-chiral silver nanoclusters. The chiral transfer from the hydrogen-bonded l- or d-tartaric acid to the nanoclusters amplified their chirality and enhanced their phosphorescence. The research is expected to inspire the preparation of metal nanocluster-based circularly polarized phosphorescent materials.

Summary: A series of chiral mechanochromic copper(I) cAAC complexes were studied to investigate the structure-property relationships for efficient triplet exciton emitters with circularly polarized luminescence. Depending on the environment, either thermally activated delayed fluorescence or phosphorescence was observed. However, chiral moieties in carbene or carbazolate ligands did not provide detectable luminescence dissymmetries. One exception was [Cu(phenoxazinyl)(cAAC)] which exhibited orange to deep red thermally activated delayed fluorescence with high radiative rate and detectable luminescence dissymmetry.

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: Recent studies have shown that the presence of oxygen around active sites is crucial for efficient electrochemical CO2-to-CO conversion. This study proposes the modulation of oxygen coordination and investigates its effects on catalytic behavior in CO2RR. By designing and synthesizing catalysts with abundant CoN4 centers and modifying their electronic structure with graphene oxide, the researchers were able to optimize the catalytic activity and selectivity for CO2 reduction to CO. The results demonstrate the importance of oxygen modulation in CO2RR and offer a novel strategy for the design of efficient electrocatalysts.

Summary: A pyrolysis-free approach was used to create a catalyst with dual Ni/Fe atomic active sites, which exhibited efficient electrochemical water splitting in both acidic and alkaline electrolytes at low overpotentials. Catalysts capable of electrochemical overall water splitting in acidic, neutral, and alkaline solution are important materials. This work developed bifunctional catalysts with single atom active sites through a pyrolysis-free route, enhancing catalytic performance and providing insights into the catalytic processes. The as-prepared catalyst showed efficient catalytic capability for electrochemical water splitting in both acidic and alkaline electrolytes, making it a promising model catalyst for mechanistic studies.

Summary: In this study, we successfully constructed a solvation-mediated self-assembly of single-crystals to helical nanofibers driven by protic acyclic (methoxy)(amino)carbenes (pAMACs) Au-I-enantiomers. The aggregation-dependent thermally activated delayed fluorescence properties were found to be attributed to packing modes of Au dimers and chains. Furthermore, the formation of extended helical Au molecular chains amplified supramolecular chirality, leading to strong CPL performance.

Summary: X-ray imaging technology has been widely applied in various fields and attracted significant attention. A high-performance X-ray scintillator with high X-ray excited luminescence (XEL) efficiency and excellent processibility and stability was developed by introducing a macrocyclic bridging ligand with aggregation-induced emission (AIE) feature into a copper iodide cluster-based metal-organic framework (MOF) scintillator. The addition of polyvinyl pyrrolidone during the synthesis process enhanced the XEL and processibility of the scintillator, resulting in a scintillator screen with excellent flexibility and stability for high-performance X-ray imaging in humid environments. For the first time, dynamic X-ray flexible imaging was achieved, allowing real-time observation of the internal structure of flexible objects with an ultrahigh resolution of 20 LP mm(-1).
