Abstract

In this paper, Schiff base (PAH) and its poly(azomethine-urethane) derivative (P-PAH) were synthesized and high-quality film sensor of these compounds could be easily fabricated on transparent polyester surface through dip-coating technique. Then, these films were used as fluorescence probes for the detection of metal ions in aqueous solutions. Photophysical properties of fluorescent films were investigated using fluorescence and UV-vis spectrometers. Fluorescence properties of probes were investigated in the presence of a series of different metal ions and the results showed that monomer and polymer films have a highly sensitive and selective response to Fe3+ ion in deionized water. Moreover, fluorescence measurements showed that the prepared fluorescent films have in the range 143-180 nm Stokes shift value. Also, contact angles of film probes were investigated and contact angles of PAH and P-PAH probes measured as 85 +/- 1 and 95 +/- 2 degrees, respectively.
