摘要: Abstract The electronic states generally characterize solids as insulators, semiconductors, or metals,1 but in some respects organic molecular crystals are an exception to ths scheme. To describe the lower energy of these solids, concepts a valence band and conduction not very useful because electrons hghly localized. These described better by Frenkel tight-binding model which progenitors crystal states.2 Generally at higher energies, present free molecule expected.3 states, ionic consist electron ionized molecule. Such may be similar exciton conducting other somewhat unique solid, e.g., ion pair hole localized on neighboring lattice sites. In spite apparent importance understanding transfer phenomena aggregat...
