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.
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。
