In this work, a novel fluorescence method for the detection of phosphate anions (PO43-) was developed based on porphyrin metalation. Through catalysis by G-quadruplex (G4), Cu2+ could insert into the porphyrins to quench their fluorescence. G4 simultaneously improved the fluorescence of the porphyrins but not that of Cu2+-porphyrin. In the absence…[Read more]
