In order to detect iron ion quickly and conveniently, a fluorescent sensor (BC-1) for iron ion bearing coumarin-benzothiazole derivative has been designed and synthesized by a novel way. Sulphur and oxygen heteroatoms were introduced as chelating site and ethyl-7-hydroxycoumarin-3-carboxylate group was introduced as fluorophore to achieve recognition. After complexing of iron ion and identification group, BC-1 which served as an ON-OFF type sensor displayed high selectivity and sensitivity for iron ion in a very short time. BC-1 was designed with ease of synthesis, low cost and low yield. Therefore, the sensor has potential in physiological and environmental applications, including connate water and industrial waste water, systems for iron ion detection.
