Summary: A series of beta-disubstituted meso-tetraphenylporphyrins and their metal complexes were synthesized and characterized. The phenylethynyl-substituted porphyrin exhibited a remarkable red shift in absorption compared to the methyl- and phenyl-disubstituted porphyrins, due to the inductive and resonance effect of the substituent groups. Single-crystal X-ray structure analysis revealed different conformations of the porphyrin core for methyl-substituted and phenylethynyl-substituted porphyrins.

Summary: The 5,7-diphenyl-8-hydroxyquinoline (5,7-Phq) ligand was synthesized and used to form novel organometallic complexes tris(5,7-diphenyl-8-quinolinolato) metal(III) [M(5,7-Phq)3; M = Al, Ga, or In] through Suzuki cross-coupling reaction. The structures of the complexes were characterized and their optical properties were investigated. The synthesized complexes exhibited red-shifted absorption and emission compared to the parent compounds, and the emission efficiency decreased with increasing atomic weight of the metal ions.

Summary: Tris(8-hydroxyquinolinate)aluminium (Alq(3)) is a widely used electroluminescent material in organic light-emitting diode technology, known to occur in five polymorphic forms. The structure of alpha-Alq(3) has been highly debated, with this study using solid-state nuclear magnetic resonance (NMR) and density functional theory (DFT) calculations to investigate. Results suggest that the previously proposed structure for alpha-Alq(3) is energetically unfavorable, with samples containing different isomeric forms exhibiting local structures consistent with specific polymorphs. Additionally, the study shows that distinguishing between mer and fac isomers based on previous assumptions may not always be accurate.

Summary: Reaction of [Ru(dmso)(4)Cl-2] with N-(4 '-R-phenyl)pyrrole-2-aldimines in refluxing toluene in the presence of triethylamine resulted in the formation of [Ru(L-R)(2)(dmso)(2)] complexes. The crystal structures revealed chelation of the aldimine ligands to the metal center and coordination of dmso through sulfur. The thermodynamic stability of the isomers was assessed using DFT calculations, and the tcc-isomer was found to be the most stable. The coordinated dmso molecules could be displaced by chelating bidentate ligands to form mixed-tris complexes of type [Ru(L-R)(2)(L-L)].

Summary: In this study, zinc oxide optical ceramics containing 0-2 wt% ytterbium were prepared, with Yb2O3 acting as an inhibitor for ZnO grain growth. The ceramics exhibit transmittance up to 60% in the visible region and their infrared transmission is determined by free charge carrier absorption. Additionally, under X-ray excitation, intense luminescence bands are observed in the blue and green regions, with Yb2O3 causing a redistribution of luminescence intensity and faster emission decay.

Summary: A new fluorinated manganese porphyrin, (Mn-TPP-p-CF3), is capable of providing dual H-1 relaxivity and F-19 NMR response to redox changes based on the Mn(III)/Mn(II) equilibrium. The properties of H-1 relaxometry and F-19 NMR make it suitable for the detection of differential redox MRI. The physical-chemical characterization shows that the Mn(III)-F distance is well tailored to allow for adequate paramagnetic effect on F-19 T-1 and T-2 relaxation times.

Summary: Different methods were used to amorphize ranolazine, a poorly soluble drug, including mechanochemistry, quench-cooling, and solvent evaporation. Cryo-milling and quench-cooling produced amorphous phases with T(g) values lower than room temperature. New forms of ranolazine, named II and III, were discovered from the relaxation of the amorphous phase produced by cryo-milling. Polymorph I, the most stable crystal form, was solved for the first time. A binary co-amorphous mixture of ranolazine and tryptophan was created, which showed higher glass transition temperature, improved kinetic stability, and increased aqueous solubility. The thermal behavior of amorphous tryptophan obtained by cryo-milling was also studied.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
