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 investigates the fluorescence properties of 3-trifluoromethyl-pyrazoles containing triphenylamine and carbazole groups, as well as their silver complexes, in both solution and solid state. The results show that the electronic coupling between triphenylamine substituent and pyrazole leads to fluorescence emission in solution, while the rigid structure of the N-ethyl carbazole substituent results in typical carbazole-centered fluorescence. Aggregation plays a major role in determining the emission properties in the solid state.

Summary: In this work, a series of novel copper(I)-iodide clusters (CuINCs) based assembly materials, including discrete cluster CuI1 and extended cluster organic frameworks MORF1 and MORF2, were successfully obtained by combining supramolecular pseudorotaxane ligands and linkers. These materials exhibit outstanding thermochromic and piezochromic luminescence properties, making them promising candidates for novel temperature and pressure sensors.

Summary: In this study, four structurally related bis-tridentate N-donor ligands with different functionalities were synthesized to form corresponding dicopper(I) complexes as catalysts for the conversion of 2,4-di-tert-butylphenol. The results showed evidence of a mu-eta(2):eta(2)-peroxo-dicopper(II) species and catalytic conversion in the imine ligand systems but not in the amine ligand systems.

Summary: Two dinuclear copper(I) iodide complexes based on a new iminephosphine tetradentate chelating ligand have been synthesized and characterized. The crystal structures of the complexes show distorted tetrahedron configurations around Cu(I) centers. These complexes exhibit bright orange-red and yellow emissions at 298 K, with excellent photo-luminescent quantum yields and short lifetimes. Reversible mechanochromic luminescent (MCL) properties of complex 2 have been confirmed by monitoring changes in emission spectra and X-ray diffraction patterns, with the unique pore structure considered to be the origin of its MCL properties.

Summary: By synthesizing dinuclear gold(I) chloride complexes with various kinds of diarsenic ligands, it was found that they can form intra- or intermolecular aurophilic interactions depending on the ligand structure. Some of the complexes showed luminescent mechanochromism and/or thermochromism, indicating a change in emission behaviors affected by the ligands.

Summary: A novel Ag-36 nanocluster with a closed electronic structure and eight valence electrons is described, which shares a similar structure with an open-shell Ag-34 nanocluster with three valence electrons, except for the replacement of two S(2-) anions with two (Ag-PPh3)(+) cations in the shell. The precise structural modulation results in varying levels of singlet oxygen photogeneration activity due to the distinct optical gaps of the nanoclusters.

Summary: This study presents the synthesis, structure, and photophysical properties of CuI complexes with a disilanylene-bridged bispyridine ligand 1. By controlling the CuI/ligand 1 ratio, dinuclear and octanuclear copper(I) complexes were prepared, exhibiting different pi stacking in crystal packing and different phosphorescence colors and efficiencies in the solid state. The differences in luminescence efficiency between the two complexes are attributed to the presence of pi stacking and different luminescence processes.

Summary: Bimetallic complexes with bridging ligands enable precise control of catalysis. This study prepared a dinuclear Rh(-i)/Rh(i) complex bridged by tridentate phosphine-phosphinine-phosphine ligands using reduction. X-ray analysis and DFT calculations showed that the phosphinine ligands adopted an unsymmetric bridging mode, accepting d-electrons from one Rh center and donating lone pairs to the other Rh center.

Summary: Three new heteroleptic cuprous complexes were synthesized using different ligands, and their structures and photophysical properties were thoroughly characterized. The absorption and emission spectra exhibited a blue-shift sequence with increasing P-Cu-P angle, and the abnormal PL emission blue-shift from 1 to 2 was attributed to steric hindrance and strong intra-molecular pi-pi stacking interactions.

Summary: Connexins (Cxs) have crucial roles in cellular communication, affecting cell homeostasis, proliferation, and differentiation. The activity and expression of Cxs are linked to various clinical conditions, including carcinomas, cardiac disorders, and wound healing. Recent discoveries on the association between Cxs and angiogenesis have sparked interest in Cx-mediated angiogenesis due to its vital functions in tissue formation, wound repair, tumor growth, and metastasis. Understanding this association may lead to the development of targeted therapies for angiogenic diseases.

Summary: In this study, a heteroleptic cuprous complex with an anionic hexafluoridophosphate was synthesized and showed excellent luminescence and low cost, making it significant for applications in display devices. Time-dependent density functional theory (TD-DFT) calculations revealed that the UV-Vis absorption of the complex was attributed to ligand-to-ligand charge transfer (LLCT) excited states. Furthermore, the paper-based film of the complex exhibited noticeable luminescence sensing for pyridine.
