dc.description.abstractResponses of organic fluorophore, perylenediimide derivative N,N'-di[3-[2-(3-thienyl)ethyl]phenyl]perylene-3,4,9,10-bis-(dicarboxyimide) (PDI1) was investigated in polymer matrix of polyvinyl chloride (PVC) by emission spectrometry. Its response to Fe(III) ions was evaluated in terms of the effect of pH. The properties of time dependent response, reversibility, limit of detection, linear concentration range for the metal ion and repeatability characteristics of the sensing element also have been studied. The offered sensor exhibited remarkable fluorescence intensity quenching at pH 6.0 in the concentration range of 1 x 10(-6) to 2.5 x 10(-3) M Fe(III) ions. The reproducibility of the sensor membrane was investigated by alternately changing the solution between 1 x 10(-4) M Fe(III) in Na2HPO4 (4 x 10(-2) M) and NaH2PO4 buffer (2 x 10(-3) M).
