reversible electronic energy transfer is instilled between chromophoric termini of the free, flexible thread as evidenced through delayed luminescence, upon rigidification of the rod the chromophores are mutually distanced and effectively decoupled. Consequently, the chromophores display their individual photophysical characteristics. The observed conformation‐dependent changes of dynamic luminescence
非生物芳香族低酰胺折叠剂在溶液中自组装形成双螺旋,可在其中心空隙中容纳双发色的线。在溶液中,可逆的电子能量转移被注入到自由的,柔性的线的发色末端之间,这通过延迟发光来证明,而在棒的刚性作用下,发色团相互隔开并有效地去耦。因此,生色团显示出其各自的光物理特性。观察到的依赖于动态发光性质的构象变化,对距离特别敏感,这为基于生命周期的分子尺度几何结构检测提供了一种新策略,通过实时发光检测导致络合物形成的分子络合物可以证明这一点。
