CHARGE AND ENERGY TRANSFER IN ORGANIC SYSTEMS.
Abstract
The electrical and photoelectrical properties of molecular crystals are described in terms of the intrinsic energy gap, EG EG is evaluated from the ionization energies of molecules, the electron affinities of molecules and the polarization energies of charges in the crystals. Each of these parameters was determined for a number of crystals. High pressure effects on electrical conduction were explained as a result. The temperature dependence of steady state currents through anthracene crystals was found to obey the 'compensation effect' which is partly explained. Exciton-excitons interactions have been shown able to explain new results on transient currents through anthracene. Motion of charges in anthracene has been established by ESR for samples doped with alkali metals. Defects in plenanthrene crystals were observed in fluorescence. (Author)
