Summary: Developing high-performance nondoped deep-blue luminescent materials for OLEDs is important yet challenging. In this study, two highly efficient pure-blue and deep-blue materials, PIPMePBO and PIPDMePBO, were designed and synthesized. The double-methyl-substituted PIPDMePBO showed nondoped deep-blue electroluminescence with high external quantum efficiency (8.0%) and minimal efficiency roll-off (approximately 12%).

Summary: Using single-crystal X-ray diffraction, we determined the crystal structures of bis(2-methoxy-3-pyridyl) diselenide and bis(2-methoxy-3-pyridyl) ditelluride. The molecules of these compounds exhibit almost perpendicular pyridine rings and different torsion angles between the two chalcogen atoms. The crystal structures show distinct packing arrangements due to the strong dispersion interaction between the pyridine rings and dichalcogenide bridges.

Summary: Crystallographic and computational studies suggest favourable interactions between polarizable arenes and halogen atoms. However, quantification of these interactions in solution has been hindered by the steric demands of the halogens. This study synthesized molecular balances and used H-1 NMR spectroscopy to quantify halogen-arene contacts in various solvents, revealing that the interaction trend is aligned with increasing exchange repulsion rather than dispersion.

Summary: In this study, a polymeric compound was synthesized and studied, with in-depth characterization of its structure, thermal stability, spectral properties, and magnetic behavior. The compound exhibited complex structural features, with a loss of water molecules over a certain temperature range and specific intermolecular interactions. ESR spectra and magnetic measurements revealed non-equivalent behavior of the Cu(II) centers connected by carboxylate groups, leading to an exchange interaction larger than their individual Zeeman energies.

Summary: Researchers designed a new carrier-free self-assembly nanomedicine Curcumin (Cur)/icariin (ICA) nanoparticles with adjustable particle size. These nanoparticles showed low cytotoxicity, high cellular uptake, sustained drug release, and the ability to inhibit inflammatory cytokine secretion and reduce cartilage degeneration. Both in vitro and in vivo experiments demonstrated that the nanoparticles had superior synergism effects in anti-inflammatory and cartilage protection compared to using Cur or ICA alone, and their retention could be monitored by autofluorescence.

Summary: This study investigates the effects and mechanisms of environmental pH and graphene edges on the adsorption properties between graphene and benzene using experimental and theoretical approaches. The results show that benzene is more likely to adsorb on the surface of graphene in acidic environments, and the adsorption performance is better in the center of graphene compared to the edges. The pH effect is influenced by changes in electrostatic interaction, while the edge effect is dominated by van der Waals interaction.

Summary: The article investigates the application of three different ligands in coordination polymers, and finds that their photophysical properties differ. One of the coordination polymers shows a high emission property, indicating its potential for the detection of the explosive compound 2,4,6-trinitrophenol (TNP) or picric acid (PA). Calculations show that CPs 2 has the highest sensitivity and selectivity towards TNP, and its ligand has the most favorable π-π stacking interaction with TNP. Additionally, the article examines the correlation between the fluorescence quenching mechanism and the structure and coordination arrangement.

Summary: This study investigated the effect of KCl and (NH4)2SO4 salts on the solubility of L-aspartic acid, L-glutamic acid, L-tryptophan, and L-tyrosine. The results showed that both salts had a salting-in effect on glutamic acid and aspartic acid, with (NH4)2SO4 having a stronger effect. For the aromatic amino acids, there was a slight increase in solubility at low salt concentrations, followed by a stronger salting-out effect, particularly with (NH4)2SO4. Furthermore, the relative solubility data were compared and a ranking connected to the amino acids' structure was established.

Summary: A new chiral NaO2Ni4O2N2 cluster with a distorted capped cubane-type structure has been synthesized and its structure has been determined by single crystal X-ray diffraction. The complex exhibits a Ni4 cubane cluster with a sodium ion anchored on its face. The coordination geometries at each metal site show local distortions, which govern the magnetic anisotropy associated with each Ni II ion. The complex also showed good catalytic activity towards bromination of aromatic phenolic compounds, achieving up to 99% conversion with 100% selectivity to their corresponding bromo derivatives.

Summary: In the solid-state, the choice of an appropriate ligand is crucial for the formation of supramolecular architecture through molecular assembly. In this study, a one-dimensional polymer is formed by the 5-phenyl-1,3,4-oxadiazole-propionate ligand and water with the help of Gd(III) metal ion. The self-assembly of these polymer chains creates an infinite two-dimensional sheet through hydrogen bonding between water ligands and the organic ligand. The formation of long pi-stacking interactions along the chain axis further stabilizes the structure.

Summary: This study investigated the application of a novel set of 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) and methyl-imidazole (MIm) coupled ionic liquids (ILs) in the Biginelli reaction. In the modified reaction, cinnamaldehyde, urea, and 1,3-diketone were condensed in the presence of 10 mol% of the DBU-MIm coupled IL catalyst at 90 degrees C, yielding dihydropyrimidinones in high to excellent yields in 45 minutes. The effect of temperature, catalytic amount, and solvent was also investigated, as well as the iminium ion mechanism and synergic role played by the [DBUH]+ and [MIm]- moieties established by DFT calculations. The easy recovery and reusability of the DBU-MIm IL catalysts make this protocol simple, benign, and reproducible for Biginelli synthesis.

Summary: Six new Ni-II complexes with different N3O donor Schiff base ligands have been synthesized and characterized, showing ferromagnetic interaction through bridging pseudohalides. The cyanate-bridged complexes have lower ferromagnetic coupling constant J compared to azide analogues due to the presence of polarizable p systems and two different N and O donor atoms. The inclusion of these new complexes in the series of mu(1,1)-NCO bridged systems allows for a detailed analysis of the magneto-structural correlation, revealing that the J value increases with an increase in bridging angles and is also influenced by the Ni1-Ni2-N-b-X-t dihedral angle.

Summary: This study synthesized two mononuclear complexes of Cu(ii) and Ni(ii) using a Schiff base ligand derived from 2-hydroxybenzaldehyde and N-methyl-propane 1,3-diamine and characterized their anti-proliferative potential against SiHa. The crystallographic results showed the orthorhombic nature for Cu(ii) complex (1), with a distorted octahedral geometry, and for complex (2), a distorted octahedral geometry with two independent Ni(ii) atoms. The complexes exhibited DNA binding affinities and promiscuous binding with Bovine serum albumin, but showed little antioxidant activity. Cytotoxicity studies revealed a decrease in cell viability for SiHa over time, while normal cell lines showed higher viability. Fluorescence imaging indicated apoptosis of the cancer cells from day 1 to day 3.
