Time-of-flight measurements on thick drop-cast films of 1,4,8,11,15,18,22,25-octakis(hexyl)phthalocyaninato zinc complex in a sandwich configuration between transparent indium tin oxide and aluminum metal electrodes have been performed. The results show that intrinsic ambipolar transport characteristics are exhibited by this very stable compound having values in the order of for both types of charge carrier. Both electron and hole transport are dispersive due to a high degree of positional disorder of the molecules.
