Abstract :
The preparation and properties of two series of polymers based on nickel complexes of the tetrathiafulvalene tetrathiolate (ttftt) of stoichiometry [(Ni-ttftt)Mxn] (M = Mn, Co, Ni, Cu, Hg; x = 0.9, 1.1, 1.0, 1.0,0.8) and [(Ni-ttftt)Lnyn (Ln = La, Sm, Eu; y = 0.7; Ln = Gd, Tb, Er; y = 0.6) are described. The insoluble amorphous polymer complexes have been characterized by elemental analysis, IR spectra, TG-DTA techniques, X-ray photoelectron spectroscopy and conductivity measurements. As compacted pellets, these complexes behave as semiconductors at 25 °C.
