摘要
A green emissive PET operating fluorescent turn-on cell permeable novel probe R1 has been successfully developed and utilized for the detection of Fe+3 in the pure aqueous system at sub-nanomolar level. Moreover, probe R1 demonstrate highly sensitive and selective towards Fe+3 over the other divalent and trivalent metal ions and was established by using fluorescence spectroscopy. The efficiency and aid of R1 was demonstrated by the fluorescence imaging of captured Fe+3 within Pollen grains by using fluorescence microscopy. These results indicate that, this is the first fluorescent turn-on PET probe to detect sub-nanomolar Fe+3 in the pure aqueous system and in cellular level.
