Abstract
Ac conductivity in the frequency range of 5 103 to 5 103 Hz of Octapheny tetrapyrazinoporphrazine Cupper (II) (OpTpPzCu) was measured, which consists of frequency independent (Dc conductivity) and frequency dependent part. This kind of conductivity results from hopping of charge carriers between localized sites around Fermi levels. The hopping sites is indication of the degree of imperfection in the crystal. The number of the hopping sites was calculated using Webb and William equation which is estimated to be 1 1020 eV-1cm-3.
