以锌卟啉-CONH-醌（ZnP-CONH-Q）配合物为探针，研制了一种高选择性的Y ~（3+）荧光传感器。ZnP-CONH-Q的Q部分与Y ~（3+）的选择性结合阻碍了电子从单重激发态（1 ZnP ~*）向Q的转移，导致荧光强度的显著增强。
A highly Y3+-selective fluorescence sensor has been developed using zinc porphyrin-CONH-quinone dyad (ZnP-CONH-Q). The selective binding of the Q moiety of ZnP-CONH-Q with Y3+ retards electron transfer from the singlet excited state (1ZnP*) to Q, leading to a remarkable enhancement of the fluorescence intensity.
