六种新型导电共轭聚合物的电化学性质研究

Electrochemistry of Six Novel Conjugated Conducting Polymers

对六种噻吩嗪聚合物进行了电化学研究,用多种方法计算了其电化学参数,并且对反应机理作以推导,估测了其能级轨道值的大小.另外,还研究了IIB金属离子与导电聚合物作用后的循环伏安现象.结果发现,IIB金属离子的引入使得聚合物的氧化峰不同程度地负移.

The electrochemical behavior of six novel conjugated polymers containing phenothiazine moieties in main chain was studied by some electrochemical techniques, and the electrode reaction processes were investigated in detail and their dynamic parameters were obtained too. In addition, the energy levels of the frontier orbits of the six polymers were calculated and analyzed. The effect characteristics of these six polymers with IIB metal ions were investigated too. The results show that these polymers all have well defined redox peaks, and the addition of metal ions shifts the oxidation peak potential of the corresponding phenothiazine group to more cathedal position.
