摘要

合成了聚(2-羰丙基)紫精(PACV)、聚(2-羟丙基)紫精(PIPV)和聚丙基紫精(PPrV).稀溶液的化学还原和光还原

第一还原态

PACV 以非缔合体

PIPV 和PPrV以二缔合体存在.聚合速率和光还原速率

PACV 最快.在PVA 膜上的光还原

三种聚紫精的第一还原态均以二缔合体存在.聚合速率和还原行为与单体和聚合物的分子结构相关.

Abstract

Polyacetonyleneviologen (PACV)

poly(2-hydroxylpropyl)viologen (PIPV) andpolypropylviologen (PPrV) have been synthesized by Menschutkin reaction.Thesynthesis rate of PACV is the fastest.The chemical reduction and photoreduc-tion of these substituted polypropylviologens in dilute aqueous solution havebeen studied.It has been found that the photoreduction rate of PACV in solutionis much higher and the produced radical cations of both PIPV and PPrV existin associated form.Howver

the photoreduction rates of these poylviologens inPVA film state are almost the same

and three kinds of the radical cationsexist in associated form.Obviously

the chemical reduction and photoreductionbehavior are related to the structure of monomers and polymers.
