2,4-Diamino-6-Hydroxypyrimidine Based Poly(azomethine-Urethane): Synthesis and Application as a Fluorescent Probe for Detection of Cu2+ in Aqueous Solution

  • Musa Kamacı

A novel poly(azomethine-urethane)-based 2,4-diamino-6-hydroxyprimidine was synthesized with chemical reaction and it designed as fluorescence probe for determination of Cu2+ in aqueous solution. The photoluminescence (PL) characteristic of the prepared Schiff base (HPAMP) and its poly(azomethine-urethane) (P-HPAMP) derivative were investigated in different polarity solvents suh as MeOH, THF and DMF. PL measurements showed that both HPAMP and P-HPAMP have higher emission intensity and Stoke’s shift value (ΔλST) in THF than the other solvents. Also, the proposed probe exhibited a specific fluorescent on response to Cu2+ over the other tested transition metal ions in aqueous solution. The sensor gave highly selective and sensetive response against Cu2+ as increasing a new emission peak at 341 nm, and possible interference and quenching effect of the other tested transition metal ions were found too low. Detection limit of Cu2+ sensor was also calculated as 7.87 × 10−6 mol L−1 in THF/deionized water (1:2, v:v).
