π-Stacking Behavior of Poly (3-hexylthiophene-2,5-diyl) s

Keywords： poly(3-hexylthiophene-2,5-diyl) , π-Stacking , CH3COOH

用可见-紫外分光光度法观察了聚(3-己烷基)噻吩(P3HexTh)在氯仿中的π-聚集行为.将乙酸、乙醇、甲醇等聚(3-己烷基)噻吩难溶溶剂加入P3HexTh的氯仿溶液时,产生比较稳定的聚合物聚集态.用直径0.20～0.01 μm滤膜过滤P3HexTh溶液的实验结果显示聚合物胶体颗粒随着溶液中乙酸量的增加而增大.金属配合物催化法合成的头对尾P3HexTh(Zn/Ni)发生π-聚集行为,而用化学氧化法合成的P3HexTh(Fe)没有出现明显的π-聚集行为.

π-Stacking behavior of poly(3-hexylthiophene-2,5-diyl) in chloroform has been studied. Addition of CH3COOH to CHCl3solutions of head-to-tail (HT) type HT-P3HexTh leads to π-stacking of the polymer molecules to form stable colloidal particles. Results of filtration experiments using membranes with 0.20 ～ 0.01 μm pores reveal their colloidal particle sizes changes following the increase of CF3COOH amounts in solutions. P3HexThs with irregular structures (P3HexTh(Fe) ) show a weaker trend to aggregate than HT-P3HexTh (Ni) .
