Summary: This study reports a self-luminescent micron europium cluster coordination polymer (Eu-CCP) cathode electrochemiluminescence (ECL) emitter for the first time. The Eu-CCP showed a high-nucleation luminescence center with a mass percentage of Eu at 50.1%. It exhibited stable and efficient ECL red emission performance, with approximately 6.5-fold higher intensity than the traditional tris(2,2 ' bipyridyl)ruthenium(II) dichloride. The enhanced luminescence of Eu-CCP was attributed to the mixed ligand and high nuclear europium luminescent center, as well as the external coreaction accelerator and coreactant enhancement.

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: A silicon-stereogenic aminosilanol with excellent diastereomeric ratio and determined absolute configuration was isolated. It was found to be configurative and condensation stable in solution, and showed stereoselective transformations in follow-up reactions, leading to the isolation of a silicon-stereogenic zinc complex and siloxane compounds. It was also discovered that there was an exchange of oxygen atoms between the silanol and water in solution, while the configuration at the silicon center remained unchanged. This study provides new analytical possibilities for studying the stereochemical courses of reactions using chiral silanols mechanistically.

Summary: Three symmetrical diacetylenes with tetraalkylammonium substituents were investigated for their polymerization and carbonization behaviors. It was found that the lack of suitable orientation hindered the formation of polydiacetylene under UV irradiation. Furthermore, the size of the cation and the anion played a crucial role in the microstructure of the resulting carbon material. The carbonized diacetylenes also exhibited potential for introducing doping elements into a graphite structure.

Summary: Luminescent N-heterocyclic carbene chloride copper (I) complexes incorporating pyrene chromophore (1-Pyrenyl-NHC-R)-Cu-Cl with different substituents (methyl or naphthyl) were synthesized and characterized. X-ray diffraction confirmed the formation of the target compounds. These compounds exhibited blue emission in both solution and solid-state at room temperature, with comparable or higher quantum yields than the parent pyrene molecule. Notably, the quantum yield was increased by almost two-fold by replacing the methyl group with a naphthyl group. These compounds show potential for applications in optical displays.

Summary: In this study, a strategy was developed to use ionogels as materials for metal extraction. The researchers first confined a commercial salt [THN]Br in silica-based ionogels and then carried out anionic metathesis to enhance their extracting efficiency or selectivity. The results showed that the ionogels could fully extract Au(III), Pt(IV), and Cr(VI), but the extraction of Co(II) was minimal. Treatment with NaDca or LiTFSI improved the extraction capabilities and allowed for separation of specific metals. Overall, the study demonstrated that ionogels can be modulated for desired extraction properties through simple anion exchange.

Summary: A new synthesis route for aromatic organosilicon-based thioether ligands was established and used to form new complexes with palladium(II) chloride. The solid-state structures favored one pair of diastereomers and could be controlled by aromatic substituents. The conformation at the sulfur atoms in solution was temperature-dependent, with a coalescence temperature at around 24 degrees C.

Summary: Cu(I)-based coordination polymers (CPs) are efficient emissive materials that provide an ecofriendly and cost-effective platform for the development of functional materials and sensors. Organic ligands play a crucial role in controlling the emissive properties of CPs. In this study, dithiane- and dithiolane-substituted triphenylamine ligands were synthesized and showed emissive properties in both solid state and solution. Coordination polymers were synthesized with Cu(I)X salts, and their emission behavior suggested ligand-centered transitions. Mechanical grinding caused emission shifts and increased intensity, potentially due to changes in the spatial arrangement of the phenyl groups and aggregation-induced quenching.

Summary: Cu(I)-based coordination polymers (CPs) are efficient emissive materials. Organic ligands and Cu(I)X salts were used to synthesize four new CPs. The emission properties of the CPs were influenced by mechanical grinding, causing shifts in emission wavelength and increased emission intensity, which may be related to changes in spatial arrangement and aggregation-induced quenching.

Summary: The development of environmentally friendly, reusable, and highly performant adsorbent materials for the removal of heavy metal ions is a big challenge in the field of wastewater treatment. In this study, ecofriendly composite materials based on alginates extracted from Sargassum sp and Turbunaria and supported on different silica particles were prepared and used as adsorbents for Ni(II) ions removal from aqueous solutions. These composites efficiently extract Ni(II) ions, surpassing the adsorption capacities of other adsorbents reported so far in the literature.
