| Abstract: | Two new anthryl-appended porphyrin dyads have been synthesized and used as highly selective and sensitive fluorescence probes for singlet oxygen ( 1O2 ). The design strategy for the probes is directed by the idea of intramolecular fluorescence resonance ener- gy transfer (FRET) interactions and carried out by incorporation of an electron-rich fluorophore (porphyrin) with a reactive anthracene for 1O2 . The molecular recognition is based on the specific interaction of 1O2 with the inner anthracene moiety, an... |
