ELECTRICAL AND MAGNETIC PROPERTIES OF NEW POLYACENE QUINONE RADICAL POLYMERS
新型聚省醌自由基高聚物的电磁性能

The several new polycene quinone radical (PAQR) co-polymers with very high Pressure resistivity coefficient were synthesized by condensation. It was experimentally found that a kink exists at about 0.11GPa on plots of log d.c. conductivity verses the square root of external pressure in a range from 0.01 to 1.0GPa; an applicable extent of Mott-T-1/4 law can expand to more high temperature region of 290-400K; there is an analogue trend of the changes between the d.c. conductivity and spin concentration and between g factor and peak-to-peak linewidth with mole fraction of 4,'4-(hexafluoroisopro-phlidene)-diphthalic anhydride (HFDA)introducecd;and the plot of log dielectric constant uersus the square root of external pressure at various temperatures does not fully obey the linear relationship theoretecally expected by Pohl.
