A functionalized OPV derivative was synthesized and applied as the fluorescent sensory material for the fabrication of a sensitive fluorescence-based iodine sensor. It was found that the sensor was much more sensitive to triiodide with the detection limit at 10-8 M. The sensor was also applied to the identification of the iodine contents in iodine-supplemented food, such as table salt and milk powder. The results show that the sensor is a promising analytical technique for more rapid and accurate analysis of iodine in the food industry.
