Solute Solvent Interaction

The radiolysis of dilute solutions of ethane-dε, propane-d8, and n-butane-d10 in liquid hydrocarbons at 195 °K results in the production of D2 and HD in amounts which are determined by the relative ionization potentials of solvent and solute. Solvents of higher ionization potential enhance the production of D2 and HD from deuterated solutes of lower ionization potential. When the ionization potentials are in the reverse order the yields are diminished. This solute–solvent interaction, which is ionic in nature, is a general phenomenon in the radiolysis of mixtures of saturated hydrocarbons in the liquid phase and is consistent with charge transfer between solvent and solute.

The fluorescence properties of various N-carbonyl-substituted indoles (compounds 1–7) are examined. The N-benzoyl-indole derivatives 1 and 3–5 are shown to fluoresce weakly and the effect of solvent polarity upon the energy of the emitting state and upon the quantum yield of fluorescence is described. It is concluded that the initially formed singlet excited state is non-emissive and can relax to an intramolecular charge transfer state which is weakly fluorescent. The solvent effects are consistent with a general type of solvent interaction, and the solvent-induced shifts in the wavelength of the fluorescence emission correlate well with the Lippert equation relating the stabilisation of the excited state to a function of solvent dielectric and refractive index. A poor correlation with the empirical ET(30) solvent polarity parameter is observed.
