Synthesis and Properties of 1,4-Bis[n 4-Diazacyclohexane Bridged Network Polymeric Phthalocyanines

Abstract

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)] diphthalonitrile with hydroquinone. The chloride derivatives of Cu(I), Ni(II) and Co(II) were employed in order to synthesize the corresponding metal - ephthalocyanine polymers. Zn(CH<inf>3</inf> CO<inf>2</inf>)<inf>2</inf> 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. © 2005 Elsevier Ltd. All rights reserved.
