ELECTRICAL AND MAGNETIC-PROPERTIES OF NEW POLYACENE QUINONE RADICAL COPOLYMERS SYNTHESIZED BY CONDENSATION

We have synthesized several new polyacene quinone radical co-polymers first by condensation and experimentally found a kink at about 1.1 (kb ar) on plots of log d.c. conductivity versus the square root of extern al pressure in a range from 0.1 to 10 (kbar); a possibility of applica tion of Mott's T1/4-law to higher temperature region (290-400K); and a nalogue trends of change between d.c. conductivity and spin concentrat ion, g factor and peak-to-peak linewidth with mole fraction of 4, 4'-( hexafluoroisopropylidene)-diphthalic anhydride (HFDA) introduced. Here , we have given the reasonable explaination of these experimental resu lts,
