本文用半经验CNDO/2量子化学计算方法研究了各种掺杂剂对聚乙炔中孤子性质的影响。掺杂剂的存在使孤子的宽度变小, 且p型掺杂剂比n型掺杂剂的影响更大, 这主要是由于掺杂剂与聚乙炔链之间的电荷转移量不同造成的。

The effect of various dopants on soliton in polyacetylene (I) was studied by semiempirical quantum chem. calculation The width of soliton became smaller when dopant was present and the effect of p-type dopants was greater than n-type dopants due to the difference in quantity of charge transfer between the dopant and I.
