Abstract The impurity content of commercial metal-free phthalocyanine (H2Pc) powder has been determined by proton-induced X-ray emission (PIXE), and high concentrations of some elements, including highly conducting iodine, were found. The effects on the impurity concentrations of heating the H2Pc to 400° C for 1, 2, 3 and 4 h were investigated. This purification procedure leads to smaller although not negligible impurity content. Some electrical properties of H2Pc were also measured as a function of purification time and it is shown that they are, as expected, greatly dependent on the impurity content.
