Abstract

5,10,15,20-Tetraferrocenyl porphyrin, H(2)TFcP, a simple example of a donor-acceptor system, was tested as ligand for the development of a novel multi-transduction chemical sensors aimed at the determination of transition metal ions. The fluorescence energy transfer between ferrocene donor and porphyrin acceptor sub-units was considered. The simultaneously measured optical and potentiometric responses of solvent polymeric membranes based on H(2)TFcP permitted the detection of lead ions in sample solutions, in the concentration range from 2.7 x 10(-7) to 3.0 x 10(-3) M. The detection limit of lead determination was 0.27 mu M, low enough to perform the direct analysis of Pb2+ in natural waters.
