Özet
The carbazole derivatives containing aromatic rings with long alkyl groups such as C-6, C-8, C-10 and 3,4-bis(4-iodophenoxy) thiophene are synthesized. The products of carbazole derivatives and 3,4-bis(4-iodophenoxy) thiophene interaction were polymerized using FeCl3 oxidant. The structural characteristics of the synthesized compounds were obtained by FT-IR and NMR spectroscopy. UV measurements are performed to determine the optical changes of the copolymers in the presence of metal ions such as Ag+, Cd2+, Co2+, Cu2+, Fe2+, Fe3+, Hg2+, Li+, Ni2+, Pb2+, Zn2+. The selectivity of Fe3+ is investigated by recording of the absorbance changes of Fe3+ solutions prepared at different concentrations. The effect of pH is also investigated in optical sensor studies. According to UV measurements, the materials containing thiophene and carbazole units can be considered as candidates for sensor production due to their selectivity towards Fe3+ ions.
