Functional Metallomacrocycles and Their Polymers 36: Synthesis and Properties of Polyester Containing a Metallophthalocyanine Ring

Abstract

<jats:p> A novel class of copolyesters containing the metallophthalocyanine ring [ M - Pc , M = Fe ( III ), Co ( II )] in the chain was synthesized by polycondensation of (dicarboxyphthalocyaninato) metal [ M - Dapc , M = Fe ( III ), Co ( II )] diacid chloride, terephthalic acid chloride and aliphatic diols. The structures of the copolyesters were characterized by infrared, electronic as well as ESR spectra, and viscosity measurement. The thermal stabilities of the polymers were evaluated by dynamic thermogravimetric analyses. The polymers obtained thus were easily soluble in chloroform, dichloromethane, etc. The green or blue colored fiber was formed by melt spinning of the copolyesters containing below 1 mol % M - Pc component. The copolyester containing Co ( II )- Pc in the chain obtained from 1,2-ethanediol as a diol component catalysed the autoxidation of 2-mercaptoethanol in the presence of oxygen. </jats:p>

Porphyrins, phthalocyanines and related systems in polymer phases

“…A series of functional Fe(III)-and Co(II)-phthalocyanines and their polymers as models for catalase, peroxidase, oxidase and oxygenase were synthesized [36]. Copolyesters 10 containing Fe(III)-and Cu(II)-phthalocyanines were obtained by polycondensation of phthalocyanine dicarboxylic acid dichlorides with terephthalic acid dichloride and aliphatic diols.…”

Preparation and nonlinear optical characterization of a novel hyperbranched poly(aryl ether ketone) end-functionalized with nickel phthalocyanine

“…Various phthalocyanine polymers, for example, stacked polyphthalocyanines for electroconductors [7,8], copolymerized phthalocyanine polymers for photoconductors [9,10], phthalocyanine polymers for catalyzers [11,12], and so on, have already been prepared. These polymers have high T g and are soluble in common organic solvent.…”

Synthesis and characterization of poly(aryl ether ketone) oligomers terminated with metallophthalocyanine to be used for oxidative decomposition of TCP

“…Recently, for improving the solubility of phthalocyanine, more attention was paid to phthalocyanine‐containing polymers. These phthalocyanine polymers, having various applications, for example, polyphthalocyanine for electroconductors and photoconductors materials,9–16 phthalocyanine polymers for magnetic materials,17 thermally stable polymers containing metallphthalocyanines,18 phthalocyanine polymers for catalyzers,19, 20 and so on, have already been prepared. Metallophthalocyanine (M‐Pc) has also attracted considerable interest because of its structural similarity to the active center of naturally occurring hemoenzymers.…”
