一个bis-helicenic三联吡啶系统的分子构象强烈修改后,绑定到锌(II)离子,一个过程,伴随着大的变化的光学和手性性质。该系统提供了一种新型的基于螺旋烯的手性光开关。
The molecular conformation of a bis-helicenic terpyridine system is strongly modified upon binding to Zn(II) ion, a process that is accompanied by large changes in the optical and chiroptical properties. This system affords a new type of helicene-based chiroptical switching.
