A Highly Sensitive Optical Sensor for Fe3+ and Cu2+ based on Diketopyrrolopyrrole: Synthesis and Spectral Investigation |
| 초록 |
Heavy and transition metal (HTM) ions have significant functions in many biological systems and environmental processes. The fluorescent probes for the recognition and the selective detection of HTM ions attract much interest in supramolecular chemistry because of the importance of these ions. Among the HTM ions, recognition of Iron (Fe3+) and copper (Cu2+) is particularly interesting because of their vital roles in biological systems. We have synthesized a series of new π-expanded diketopyrrolopyrrole (DPP)-based fluorescent probes for selective recognition of Fe3+/Cu2+ over a wide range of metal ions. The probe exhibited pronounced on–off type fluoroionophoric properties with significant color change. Both UV-Vis and fluorescence spectroscopic studies demonstrated that probe was highly sensitive and selective towards Fe3+/Cu2+. |
