It is of great importance to design a fluorescent sensor with high selectivity, sensitivity and large Stokes shift to zinc detection for environmental water sample and in vivo. Herein, A novel Zn2+ fluorescent sensor with larger Stokes shift (110 nm) 1-((5-(4-(diphenylamino)phenyl)pyridine-2-imino)methyl)naphtha lene-2-ol (abbr. TPA-PN) was designed and synthesized. In DMF-H2O (V: V = 1: 1, pH = 7.0) solution, it could achieve high selectivity and sensitivity to Zn2+, there was a linear responsive range of 0-20 mu M of concentration of Zn2+ ions for the sensor, the detection limit was as low a...
