我们报告的大分子螺旋复制的第一个例子。一种光学活性的螺旋和阴离子的聚（4-羧基苯基异腈）的钠盐，被发现作为模板，在不同的螺旋与相反的电荷在水中，导致在互聚物的螺旋组装与控制的螺旋进一步螺旋诱导。考察了pH值和盐浓度对螺旋度诱导的影响。
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.
