Synthesis and electric properties of one-dimensional polymers of metallophthalocyanine with octakis-substituents of acceptor groups

One-dimensional metallophthalocyanine polymers adopt a favorable conformation for the enhancement of electric conductivity. Metallophthalocyanine derivatives with octakis-substituents of donor or acceptor groups, especially with octa-cyano substituents as acceptor groups are also known to increase the electric conductivity. In the present study, octacyanometallophthalocyanine (MPcOC, M=Si, Fe) monomeric and polymeric complexes were synthesized and their electric and electrochemical properties were investigated. Each complex showed reversible redox wave at near 0 volt, exhibiting the strong acceptor properties. The polymeric complexes gave electric conductivity of 10(-6) S/cm without any doping process.
