摘要
本文以聚丁(对甲苯硫酸)-2,4-己二炔-1,6-二醇酯[polylbis(p-toluene sulphonate)ester of 2,4-hexadiyne-1,6-diole](PDA-TS)为例,对含有共轭三键的共聚物-聚丁二炔(polydiacetylene’s)(PDA’s)中光生载流子的产生机制,进行了初步探讨,认为其中的光生载流子分别由最初产生的电子-空穴对的分解和其后通过驰豫所形成的极化子-激子的离化而产生,对PDA-TS中三重激子的形成及其特点进行了详细的分析。
In this paper, the mechanism of photo-carrier generation in polymer with conjugated
triple bond-poly(bis(p-toluene sulphonate)ester of 2,4-hexadiyne-l,6-diole)(PDA-TS) is
studied. We infer that photo-carriers are generated by dissociation electron-hole pairs which were produced by photo-excitation initially, and by thermalization of polaron-excitons which were formed through relaxation, respectively, The formation and characters of triple exciton in PDA-TS are analyzed in detail.
