Oxygen molecules were found to enter into lead phthalocyanine single crystals by thermal diffusion when they were annealed in an oxygen gas of atmospheric pressure above 230℃ for more than ten hours. Diffusion constant is 7.2×10^<-9> cm^2sce^<-1> at 242℃ with activation energy of 1.4eV. Dark conductivity σ increased by three orders of magnitude at room temperature with the heat treatment. Correspondingly, activation energy of conductivity E defined by σ∝exp(-E/kT) decreased from 0.85 to 0.54eV. The measurement of thermoelectric power indicates that positively charge carriers are generated in the presence of oxygen. The experimental results are explained on the model that an oxygen molecule acts as a center of carrier generation by accepting an electron from a neighboring lead phthalocyanine molecule and releasing the hole-like carrier.
