自1977年对聚乙炔掺杂获得成功后,人们发现很多高分子共轭聚合物都可通过掺杂而使其电导率大大提高,目前聚乙炔掺杂后的电导率已达到了铜的水平;由于聚丁二炔是一种比较复杂的结构,每个单胞内含一个共轭三键,且是唯一能获得大块单晶的高聚物,如果能对它进行掺杂而使电导率大大提高的话,将在制造有机半导体器件等方面显示出巨大的应用前景,可惜的是,至今对它掺杂未获得成功;这表明它有着不同于其他高聚物的掺杂机理.对于聚丁二炔的掺杂和电导,实验资料很少,理论模型还末见报导、本文在详细分析实验事实的基础上,第一次采用Green函数的方法,推导出了求掺杂(低掺杂)后的聚丁二炔的电导率的公式,并进行了数值计算,与实验事实较好地符合.
Since the success of polyacetylene doping in 1977, it was found that many polymer conjugated polymers can be greatly increased by doping conductivity, the conductivity of polyacetylene doped copper has now reached the level; As polydiarytyne is a more complex structure, each unit cell contains a conjugated triple bond, and is the only polymer to obtain a large single crystal, if it can be doped so that the conductivity Greatly increased, it will show great promise in the field of manufacturing organic semiconductor devices, etc. However, its doping has so far failed to be successful; it shows that it has a different doping mechanism from other polymers. Doping and conductance of diyne, the experimental data are few, and theoretical models are also reported in the end. Based on the detailed analysis of the experimental facts, this paper first uses the Green function method to derive the doping (low doping) The conductivity of the polybutadiene after the formula, and carried out numerical calculations, and the experimental facts are in good agreement.
