Fluorine Containing Nonsymmetrical Five-Ring Achiral Banana-Shaped Compounds With Columnar and Synclinic Antiferroelectric Layered Phases
The phase transitional behavior of two homologous series of five-ring banana-shaped compounds comprising fluorine substituents synthesized through covalent linking of two chemically dissimilar rod-like anisometric cores (arms) to central 1,3-phenylene is reported. The novelty of these molecules originates from the fact that the molecules are highly nonsymmetrical. One of the arms, which is eith...
متن کاملThermochemistry of Organic Fluorine Compounds and Carbon Compounds
Rotating-bomb calorimetry was first applied to organic compounds that contain chlorine, bromine, or sulphur. Techniques developed for these classes of compounds, mostly at the University of Lund and at the Bureau of Mines in Bartlesville, have been described in the book Experimental Thermochemistry-, The development of rotating-bomb methods made accurate combustion calorimetry feasible for othe...
متن کامل[Health effects of fluorine and its compounds].
Fluoride, the ionic form of fluorine, is a natural component of the biosphere and 13th most abundant element in the crust of the earth. It is, therefore, found in a wide range of concentrations in virtually all inanimate and living things. Many trace elements perform a definite function in human metabolism and the question of the value of fluoride, always found in the body, has been raised. Muc...
متن کامل14-Electron Four-Coordinate Ru(II) Carbyl Complexes and Their Five-Coordinate Precursors: Synthesis, Double Agostic Interactions, and Reactivity
The structure of five-coordinate Ru(II) complexes RuHCl(CO)(PPr3)2, 1, RuCl2(CO)(PPr3)2, 2, and Ru(Ph)Cl(CO)(PBu2Me)2, 12, are reported. All three of these complexes have square-based pyramid geometry with the strongest σ-donor ligand trans to the vacant site. These 16-electron complexes do not show bona fide agostic interactions. This is attributed to the strong trans influence ligand (H, CO, ...
متن کاملAnomalous diffusion of fluorine in silicon
The diffusion of ion implanted F in Si has been studied by the use of secondary ion mass spectroscopy and thermal desorption spectroscopy. In the dose range studied (below amorphization threshold), F exhibits an anomalous out-diffusion behavior which is characterized by the depletion of F in Si substrate at temperatures 2550 “C! with complete suppression of diffusion deeper into the bulk of Si....
