合成了具有旋光轮结构的轮烷侧链聚乙炔,通过轮结构的位置控制实现了对螺旋结构的可逆结构控制。只有当旋光轮组件移动到主链附近时,聚乙炔才形成单手螺旋结构。
Polyacetylene bearing a pendant rotaxane moiety with an optically active wheel component was synthesized to realize reversible structural control of its helical structure by position control of the wheel component. Polyacetylene formed a one-handed helical structure only when the optically active wheel component moved close to the main chain.
