摘　　要：合成了三种新型的主链为聚４－乙烯基吡啶的侧链型紫精聚合物和相应的小分子紫精，研究了它们的电还原及光还原行为。结果表明这类侧链型紫精聚合物的电还原和在异丙醇水溶液中的光还原都存在明显的聚合物效应，还原后生成的自由基正离子分子内缔合的倾向比相应的小分子紫精大得多．Three new types of side chain polyviologen, using poly 4-vinyl pyridine as main chain, were synthesized and their electroredox and photoreduction behaviors were investigated. Either in electroredox or in photoreduction carried in 2-propanol aqueous solution, the“polymer effect” is significant for these side chain polyviologens. The intramolecular association tendency of reduced radical canons is much greater than that of the respective low molecular viologen.
