Synthesis and properties of 1,4-bis[N-(2-tolylsulphonylaminoethyl)]-1,4-diazacyclohexane bridged network polymeric phthalocyanines

1,4-Bis[N-(2-tolylsulphonylaminoethyl)]-1,4-diazacyclohexane bridged metal-free and metal phthalocyanine polymers were prepared. The metal-free phthalocyanine polymer was obtained by the reaction of 4,4'-[2,2'-(piperidine-1.4-diyldiethylene)di(tosylimino)ldiphthalonitrile with hydroquinone. The chloride derivatives of Cu(I), Ni(II) and Co(II) were employed in order to synthesize the corresponding metal-phthalocyanine polymers. Zn(CH3CO2)2 was used for the preparation of the zincphthalocyanine polymer. For the preparation of the Co-containing polymer, ammonium molybdate had to be added as catalyst. The new polymers have been characterized by elemental analysis, IR, NMR, UV-VIS and DTA. (c) 2005 Elsevier Ltd. All rights reserved.
