Benzofuran and Naphthofuran based chemosensors for metal ion detection using fluoroscence spectroscopy

Sonia Ali, Sakshi Joshi and Jyoti Agarwal*

With the advancement in the field of agriculture and industrial regime, numerous metals such as lead, cadmium, mercury, zinc, copper, arsenic, etc. are released into the environment as effluent. These metal ions enter water bodies and generate many health issues. Considering their harmful impact on human lives, numerous fluorescent probes have been developed in recent years to detect the presence of these metal ions. The fluorescent probes are used owing to their ease of operation, good selectivity, and high sensitivity. The interaction between functional groups present in the structural framework of the probe and the empty orbitals of metal ions is responsible for the chemo selectivity of the probe. This report summarizes the organic probes which possess benzofuran and naphthofuran moieties and act as fluorescent chemosensors toward metal ions. The selectivity and sensitivity of these chemosensors along with the limit of detection have also been discussed.
