Phonon Anharmonicity of Ionic Compounds and Metals
Vibrational studies of materials at elevated temperatures are relatively rare, and most phonon work also has emphasized harmonic behavior. Non-harmonic effects are often unexplored. These non-harmonic effects can be important for many properties of the material, such as thermal transport and phase stability. Phonon theory and computational methods are briefly reviewed, and the experimental tech...
متن کاملSynthesis and spectroscopic properties of β-meso directly linked porphyrin–corrole hybrid compounds
The preparation of β-meso directly linked porphyrin-corrole hybrids was realized for the first time via an InCl3-catalyzed condensation reaction of 2-formyl-5,10,15,20-tetraphenylporphyrins with meso-substituted dipyrromethanes. Hybrid compounds have been characterized by 1H NMR, 13C NMR, 2D NMR, UV-vis absorption and fluorescence spectroscopy.
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
