| Perfluoro compounds have been utilized in many fields of science due to its unique nature which is otherwise unattainable. A recent hot topic in the perfluoro regime, so-called "a fluorous phase technique" has emerged from the environmental concerns and its idea has disseminated into various fronts of chemistry. The characteristics coined by the words "fluorophilic" or "fluorophobic" renders the perfluoro compounds to form a fluorous phase which is a phase immiscible not only with water or hydrophilic polar solvents but also with non-polar hydrophobic solvents such as hydrocarbons. Phase separations between water and hydrocarbons or perfluorocarbons are clearly explained by the exclusion of hydrocarbons or perfluorocarbons from the hydrogen bonding network of water. However, there has been no plausible explanation for the phase separation between hydrocarbons and perfluorocarbons. To clarify the phase separation mechanism of hydrocarbons and perfluorocarbons, we have investigated the molecular interaction between hydrocarbons and perfluorocarbons by ab initio molecular orbital calculations and the density functional theory calculations. |
