Electrical properties of the conducting polydiacetylene poly-1,1,6,6-tetraphenylhexadiinediamine

Abstract

The electrical properties of the conducting polydiacetylene poly-1,1,6,6-tetraphenylhexadiinediamine (poly-THD) are investigated for the first time. The stability of the conductivity with time, the current-voltage characteristics over a broad range of applied voltages, the pressure dependence of the conductivity, and the low-frequency conductivity fluctuations in the range of analysis frequencies 20 Hz–10 kHz are studied. Appreciable anisotropy of the conductivity is discovered under strong uniaxial compression. Hooge’s parameter α is evaluated (α∼20 at 300 K).
