Abstract
We have used PET chemosensors in the determination of N-carbamoylglycine. When N-carbam-oylglycine reacts with complex already made by the fluorophore and metal ion, the luminescence intensity can be changed and this phenomenon can be utilized in quantification. We used three metal ions, $Zn^{2+}$, $Ni^{2+}$, $Cu^{2+}$ and in order to investigate selectivity an acetic acid was used. $Ni^{2+}$ ion showed change in the eT mechanism by the anions. $Cu^{2+}$ ion showed the ability to distinguish N-carbamoylglycine from an acetic acid and it is noteworthy that $Zn^{2+}$ ion can change luminescence sensitively according to concentration.
