Abstract

A novel polymeric metal-free phthalocyanine (M = 2H) and its metal complexes (M = Zn, Cu, Co and Ni) were prepared by the tetramerization reaction of 3,6,9-Tris(p-tolylsulfonyl)-1,11-bis(3,4-dicyanophenoxy)-3,6,9-triazaundecane 5 with the appropriate materials. The electrical conductivities of the metal-free phthalocyanine and the metal complexes, measured in air, were found to be similar to 10(-6)-10(-5) S m(-1). The aggregation property of the zinc complex 7 was investigated with Ni(2+), Cu(2+). Co(2+), Pb(2+), Cd(2+) and Ag(+) cations. Thermal analysis of the polymers were done by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA) at a heating rate of 10 degrees C min(-1) under a nitrogen atmosphere, All the novel compounds were characterized by using elemental analysis, UV-Vis, FT-IR, NMR and MS spectral data and DSC, DTA/TG techniques.
