Optically active luminophores capable of emitting circularly polarized light (CPL) are keys in many photonic communication systems. Herein, we report a new cryptochiral CPL‐functioned molecular system composed of a C₂‐symmetric 5,5’,6,6’,7,7’,8,8’‐octahydro‐1,1’‐bi‐2‐naphthyl rotamer bearing two flexible linkers attached to two pyrene rings as emitters. Despite exhibiting negligibly weak circular‐dichroism (CD) signals in the ground state, the luminophore displayed a clear CPL signal in the photoexcited state.

带有两个软基P的基极联芳旋转体，在基态下具有隐性手性特征

能够发射圆偏振光（CPL）的旋光发光体是许多光子通信系统中的关键。在此，我们报告了一个由C ₂对称的5,5'，6,6'，7,7'，8,8'-八氢-1,1'-bi-2-2-组成的新的由手性CPL作用的分子系统。萘基旋转异构体，带有两个连接在两个pyr环上的柔性连接基作为发射体。尽管在基态下可显示出微弱的圆二色性（CD）信号，但发光体在光激发态下仍显示出清晰的CPL信号。
