In this research Chloroalminium and Copper Phthalocyanine (CIAIPc and CuPc) were purified twice, using entrained sublimitation techniques. Ohmic contacts were made on the samples using the electrical properties of both (CIAIPc and CuPc) were studied over a range of temperatures. The activation energies of these materials were measured using both forward and reverse current-voltage characteristic and then they were compared. It was found that CIAIPc has a lower activation energy than CuPc. Further, I found that in CIAIPc, the activation energies evaluated using forward and reverse bias differ significantly at low temperatures while in CuPc this did not occur.
