A chiral cage is proposed as an effective chiroptical sensor for perrhenate (surrogate for TcO) in water, fruit juice and artificial urine media. The key mechanism for the chiroptical sensing resides in the change of dihedral angle of the binaphthyl unit and H-bonds with the guest, resulting in ample changes of the CD signal as a consequence of the binding event.
手性笼被提议作为水中、果汁和人工尿液介质中高氚酸盐（TcO 的替代物）的有效手性光学传感器。手性光学传感的关键机制在于联萘单元的二面角和氢键与客体的变化，导致结合事件后 CD 信号发生充分变化。
