SYNTHESIS AND CHARACTERIZATION OF NEW TETRAAZA-BRIDGED POLYMERIC PHTHALOCYANINES

New tetraaza-bridged metal-free and metal phthalocyanine polymers were prepared. The metal-free phthalocyanine polymer was obtained by the r eaction of olysulphonyl-1,5,8,12-tetraamine)-diphthalonitrile with hyd roquinone. The chlorides of Cu(II), Ni(II) and Co(II) were employed in order to synthesize the corresponding metal-phthalocyanine polymer, Z n(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 p reparation of the Go-containing polymer, ammonium molybdate had to be added as catalyst. The new polymers have been characterized by element al analyses, IR, NMR and UV-VIS spectroscopy. The electrical conductiv ities of the phthalocyanine polymers measured as gold sandwiches are a bout 10(-9) Sm-1 in vacuo and 10(-8) Sm-1 in air. (C) 1997 Elsevier Sc ience Ltd.
