Abstract

A highly Y³⁺-selective fluorescence sensor has been developed using zinc porphyrin-CONH-quinone dyad (ZnP-CONH-Q). The selective binding of the Q moietyof 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.
