Photoconductivity of solutions

Slope to Intercept Values of Single Photon Ionization of Solutes in Hydrocarbon Solvents at Room Temperature 

The decrease in ionization energy in solution is due to the effect of I1 which is always greater than I Vq I. If the same solute is measured in different hydrocarbons, approximately the same polarization energy should result, since is approximately 2 for most of the hydrocarbons. In Table 5, the polarization energies of the positive anthracene ion in three different solvents are given. A value of -1.06 eV is obtained for all three solvents which is an indication that the anion radius is constant, since Er is approximately the same for the three liquids.

Photoconductivity measurements on solutions of fullerenes in alkanes gave a greater reduction of the ionization energy than expected from the van der Waals diameter of the molecule (Katoh et al., 1994). 

The availability of photons of the X-ray region at electron storage rings allows the excitation of electrons from inner shells of suitable solute molecules. First reports on the photoconductivity of organometallics in hydrocarbon solution are attributed to Sham (1988).
