Abstract
In this study, a novel tetrapyrazinoporphyrazine-based fluorescent sensor for Cu2+ ion was synthesized and fully characterized by H-1 NMR, MALDI-TOF MS, and elemental analysis. A tetrapyrazinoporphyrazine substituent was used as the reporting group and a 2,2'-dipyridylamine moiety was employed as the recognition group. The effects of various metal ions on the absorption and emission spectra of the designed molecule were investigated, demonstrating that this compound shows selectivity and sensitivity toward the Cu2+ ion. Upon addition of Cu2+ ion, a fluorescent intensity of the tetrapyrazinoporphyrazine-based sensor decreased gradually at 655 nm. To confirm a selective binding ability of 2,2'-dipyridylamine moiety toward Cu2+ ion, a comparative study was performed using tetrapyrazinoporphyrazine derivative with bromine instead of 2,2'-dipyridylamine moiety. Furthermore, association constant and detection limit value of the synthesized compound toward Cu2+ ion were derived from a repetitive titration experiment. Also, a reversibility of the prepared sensor was confirmed through additional test using compound and ethylenediaminetetraacetic acid.
