摘要

我们首先通过缩合法合成了几种新的聚苯二烯醌自由基共聚物，并在实验中发现，在0.1至10 kbar范围内，对数直流电导率与外部压力的平方根的关系图中，在1.1 kbar左右存在扭结。考虑了Mott’s T/sup 1/4/定律在290 ~ 400 K高温区应用的可能性，并分析了为提高稳定性而加入4,4′(六氟异丙二苯二酸酐)(HFDA)的摩尔分数下，直流电导率与自旋浓度的变化趋势。对数介电常数与压力平方根的关系并不完全符合波尔所期望的线性关系。本文对这些实验结果作了合理的解释。

Study of pressure and temperature dependence of electrical properties in new intrinsic semiconducting polyacene quinone radical polymer

We have synthesized several new polyacene quinone radical co-polymers first by condensation and experimentally found a kink at about 1.1 kbar on plots of log d.c. conductivity versus the square root of external pressure in a range from 0.1 to 10 kbar. we consider the possibility of the application of Mott's T/sup 1/4/ law to the higher temperature region of 290-400 K and analyse trends of change between d.c conductivity and spin concentration with mole fraction of 4,4'(hexafluoroisopropylidene diphthalic anhydride) (HFDA) (introduced to improve the stability). Plots of log dielectric constant versus the square root of pressure do not fully obey the linear relationship expected by Pohl. Here we give a reasonable explanation of these experimental results.
