A fluorescent polyurethane foam was obtained by incorporating synthesized rhodamine salicylaldehyde, which was used for fluorescence sensing of Fe3+. The foam exhibited high sensitivity and good selectivity towards Fe3+ in pure water.
Rhodamine salicylaldehyde was synthesized, and its structure was determined using Fourier transform infrared spectroscopy, H-1 NMR analysis as well as electrospray ionization mass spectrometry. Then a fluorescent polyurethane foam was obtained via incorporation of the prepared rhodamine salicylaldehyde, and the fluorescence sensing behavior for Fe3+ was systematically investigated. Results showed that the fluorescent polyurethane foam produced higher fluorescence in the presence of Fe3+ in pure water, due to the coordination for Fe3+ binding leading to ring-opened amide form. The limit of detection was calculated to be 1.64 x 10(-6) mol L-1. This fluorescent polyurethane foam can also recognize Fe3+ with good selectivity. (c) 2021 Society of Industrial Chemistry.
