摘要
合成了一系列 1,2_二 (N_取代_4_吡啶盐 )乙烯类聚合物 (简称PBE) ,研究了其紫外可见光谱性质及化学还原行为 .探讨了PBE在还原剂Na2 S2 O4 存在下发生不可逆氧化还原反应的还原机理 。
The ultraviolet-visible spectroscopy and chemical reduction behavior of a series of synthesized 1,2-di(N-substituted-4-pyridinium)ethylene polymer (abbreviated as PBE)are studied in this article. It is discovered that irreversible oxidation-reduction reaction of PBE polymer occurs in the presence of Na 2S 2O 4. The mechanism of reduction reaction is preliminarily discussed and the effect of the molecular structure on the stability of intermediates is also described.
