Abstract :
The authors measured the DC conductivity of two polyacene quinone radical type polymers as a function of pressure at various temperatures. It was found that there is a kink at about 2.5 kbar on plots of log conductivity versus the square root of applied pressure in the range from 0.6 to 10 kbar, and that DC conductivity-temperature curves, even in the higher temperature region (300-400 K), also obey Mott´s T1/4 -law. This may be due to the jump of an electron to the state nearer in space with a considerable energy barrier
