Synthesis and characterization of new tetraaza-bridged polymeric phthalocyanines
Özet
New tetraaza-bridged metal-free and metal phthalocyanine polymers were prepared. The metal-free phthalocyanine polymer was obtained by the reaction of 4,4'-(octane-1,5,8,12-tetra-p-tolysulphonyl-1,5,8,12-tetraamine)-diphthalonitrile with hydroquinone. The chlorides of Cu(II), Ni(II) and Co(II) were employed in order to synthesize the corresponding metal-phthalocyanine polymer, Zn(CH3CO2)(2) was used for the preparation of the zinc phthalocyanine, and Fe(CO)(5) was used for the preparation of the Fe-analog. For the preparation of the Go-containing polymer, ammonium molybdate had to be added as catalyst. The new polymers have been characterized by elemental analyses, IR, NMR and UV-VIS spectroscopy. The electrical conductivities of the phthalocyanine polymers measured as gold sandwiches are about 10(-9) Sm-1 in vacuo and 10(-8) Sm-1 in air. (C) 1997 Elsevier Science Ltd.
