Abstract:

The report is devoted to the synthesis and study of polymeric phthalocyanines formed as the result of the polycoordination of 1, 2, 4, 5-tetracyanobenzene and its mixtures with phthalonitrile by interaction with powdered copper or its monochloride Cu2Cl2. The synthesis was carried out with the objective of elucidating the effect of the oxygen-containing groups and the branching of the molecular structure on the electrophysical properties of the polymers. It was shown that polymers synthesized from tetracyanobenzene possess and electroconductivity at 300K of 0.00001 . 100ohmcm at E 6 kcalmole as compared with the polyphthalocyanines from pyromelitic acid with a conductivity of 0.0001ohm at E 4.2 kcalmole. The electroconductivity of tetracyanobenzene- phthalonitrile copolymers treated with H2SO4, accompanied by hydrolysis of the nitrile groups, is 0.00001 and 10 to the -2.6 powerohmcm for reprecipitated and non-reprecipitated specimens, respectively. A study of the thermostability of the synthesized polyphthalocyanines showed that specimens of the polymer which during treatment underwent hydrolysis of the nitrile groups, break down in air as a rule at higher temperature than the nitrile-containing analogs.
