ELECTRICAL-PROPERTIES OF THE CONDUCTING POLYDIACETYLENE POLY-1,1,6,6-TETRAPHENYLHEXADIINEDIAMINE

The electrical properties of the conducting polydiacetylene poly-1,1,6 ,6-tetraphenylhexadiinediamine (poly-THD) are investigated for the fir st time, The stability of the conductivity with time, the current-volt age characteristics over a broad range of applied voltages, the pressu re dependence of the conductivity, and the low-frequency conductivity fluctuations in the range of analysis frequencies 20 Hz-10 kHz are stu died. Appreciable anisotropy of the conductivity is discovered under s trong uniaxial compression. Hooge's parameter tu is evaluated (alpha s imilar to 20 at 300 K). (C) 1997 American Institute of Physics.
