  • Title: An yttrium ion-selective fluorescence sensor based on metal ion-controlled photoinduced electron transfer in zinc porphyrin-quinone dyad.
    Author: Okamoto K, Fukuzumi S.
    Journal: J Am Chem Soc; 2004 Nov 03; 126(43):13922-3. PubMed ID: 15506743.
    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 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.
