Vicinal fluorine-fluorine coupling constants: Fourier analysis
The Journal of Chemical Physics, 2004Stereochemical dependences of vicinal fluorine-fluorine nuclear magnetic resonance coupling constants (3JFF) have been studied with the multiconfigurational self-consistent field in the restricted active space approach, with the second-order polarization propagator approximation (SOPPA), and with density functional theory.

Fluorinations Not Using Fluorine Gas
2022The introduction of fluorine in pharmaceuticals and agrochemicals can be highly advantageous. The substitution of one or just a few hydrogen atoms by fluorine can dramatically alter a compounds acidity/basicity and lipophilicity, which may result in an improvement of its biological and/or pharmaceutical properties.

Fluorinated nanocarbons using fluorinating agent: Strategies of fluorination and applications
The European Physical Journal B, 2009The fluorination method strongly influences the physical properties of the resulting fluorinated carbon materials. Two fluorination ways, direct fluorination under pure fluorine gas and controlled fluorination by the decomposition of TbF4, have been used for the fluorination of particular nanocarbons: carbon nanofibers and a mixture of carbon nanodiscs

Fluorinated and semi-fluorinated surfactants
1997Surfactants which contain one or more fluorinated or partially fluorinated hydrophobic groups (fluorinated surfactants or ‘fluorosurfactants’) can show dramatically different properties to those of hydrocarbon surfactants. The special properties of fluorosurfactants, which result from the unique properties of fluorocarbon chains, makes them ...
