Geminate Charge-Pair Recombination in Molecular Crystals

  • C. L. Braun
  • R. R. Chance


Intrinsic photoconductivity is now known in a number of molecular crystals. Beginning with the work of Castro and Hornig which established a threshold of 4.0 eV for anthracene,1 values of 3.0 eV for naphthacene,2 3.8 eV for pyrene,3 4.9 eV for phenanthrene,4 and 5.2 eV for naphthalene5 have been measured. These values may be rationalized in at least semi-quantitative fashion using the ideas of Lyons6 together with gas phase and crystal ionization potentials plus free molecule electron affinities.
