Preparation and properties of polymeric conductive nickel complexes of tetrathiafulvalene tetrathiolate ligand

摘要

The preparation and properties of two series of polymers based on nickel complexes of the tetrathiafulvalene tetrathiolate (ttftt) of stoichiometry [ (Ni-ttftt)M-x](n) (M = Mn, Co, Ni, Cu, Hg; x = 0.9, 1.1, 1.0, 1.0, 0.8) and [ (Ni-ttftt) Ln(y)](n) (Ln = La, Sm, Eu; y = 0.7; Ln = Gd, TD, 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 degrees C. (C) 1998 Elsevier Science S.A. All rights reserved. [References: 19]
