Abstract

We report the first example of the replication of macromolecular helicity. An optically active helical and anionic polyelectrolyte, the sodium salt of poly(4-carboxyphenyl isocyanide), was found to serve as the template for further helicity induction in a different polyelectrolyte with opposite charges in water, resulting in interpolymer helical assemblies with controlled helicity. The effects of the pH and salt concentration on the helicity induction were investigated.

摘要

我们报道了大分子螺旋性复制的首个实例。一种旋光性螺旋状阴离子聚电解质——聚（4 - 羧基苯基异氰化物）钠盐，被发现可作为模板，在水中诱导另一种带相反电荷的不同聚电解质产生螺旋性，从而形成具有可控螺旋性的聚合物间螺旋组装体。研究了pH值和盐浓度对螺旋性诱导的影响。
