Lead is known to be one of the most abundant of the heavy metals. It is widely distributed and mobilized in the environment due to its extensive usage in industries like batteries, gasoline, cable and pigments, besides in our daily lives.
In this chapter, the photochemical changes in the sensing modules are based on the photo-induced electron transfer (PET) has been discussed.
The sensors which operating according to this mechanism are known as chelation-enhanced fluores-cence (CHEF)-type sensors.
The selective recognition behaviour for Pb2+ was achieved in aqueous/organic solvent system (CH3CN/H2O/DMSO, 1000:50:1, v/v). The complexation of Pb2+ induced an enhancement of the monomer emission of pyrene.
