Synthesis, characterization, aggregation and thermal properties of a novel polymeric metal-free phthalocyanine and its metal complexes
چکیده انگلیسی

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 ∼10−6–10−5 S m−1. The aggregation property of the zinc complex 7 was investigated with Ni2+, Cu2+, Co2+, Pb2+, Cd2+ 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 °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.

The novel metal-free (6) and its metal complexes (7–10), containing triazadioxa peripheral units, have been prepared and characterized. The electrical conductivities, thermal and aggregation properties of the novel polymers were also investigated.Figure optionsDownload as PowerPoint slide
