FIH sensor-based fluorescence was fabricated and analyzed employing 1H, 13C-, APT-NMR, elemental analysis and ATR-FTIR spectroscopy. The fluorescence properties of the fabricated FIH sensor towards metal ions were investigated by fluorescence spectroscopy. It was determined that prepared sensor had the highest fluorescence sensitivity towards Zn2+ ions which was 35 times more than other metal ions (Ag+, Li+, Ba2+, Mg2+, Cu2+, Ni2+, Cr3+, Pb2+, Ca2+, Fe2+, Fe3+, Co2+, Hg2+, Cd2+, Rb2+, Cs2+, and Al3+) while it was being no effect for the commonly used metal ions. From the point of this view, it can be easily said that this system can be applied as fluorescence sensor for Zn2+ ions.
