Rigid chain polymer can be named as soft confined polymer because the confine results from the chain itself. 其中刚性链段的运动受其刚性的限制亦被称为软受限高分子。
Rigid conjugated main chain is an important feature of conjugated polymers, it can formed large conjugated π electron system, so that the charge can transfer within the molecule. Thus, a single quencher molecule can cause a super-quenching of the entire polymer chain. 含有刚性共轭主链是共轭聚合物的重要特征,能在分子内形成大的共轭π电子体系,从而使电荷在分子内进行传输,单个猝灭剂分子就足以引起聚合物荧光的超猝灭。
