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 metalphthalocyanine 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 Co-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. © 1997 Elsevier Science Ltd.
