【 摘 要 】

The alternative current (Ac) conductivity of octaphynyl tetrapyrrazino porphrazine Zinc (opTpPzZn) was measured in the frequency rate of 5 × 103 to 5 ×103 Hz of and temperature rate (303 to 423)k. The dc conductivity was carry out in the same temperature range, which consists of frequency independent (Dc conductivity) and frequency dependent part. This type of conductivity results from hopping of cargo carriers between localized sites around Fermi levels. The jump position is indication of the degree of imperfection in the crystal. of crystallation degree . The number of the jump position was calculated using Webb and William equation which is estimated to be 1 × 1020ev-1cm3.
