✦ Synopsis

Improvement of electrical conductivity was attempted by polymerizing octacyanometallophthalocyanine (MPcOC; M ≡ Fe , Co ) units into one-dimensional molecular complexes. The synthetic route to MPcOC was established by reacting tetracyanobenzene with a metal(II) acetate in sulfolane. Poly(μ-pyrazine)octacyanophthalocyaninatoiron(II) and -cobalt(II) were synthesized and their doping with lithium was carried out. The Fe (II) and Co (II) octacyanophthalocyanine complexes showed good electrical conductivities of the order of 10^-8^-10^-4^ S cm ^-1^. The electrical conductivities of the lithium-doped complexes were improved by two or three orders of magnitude in comparison with the corresponding monomeric and polymeric complexes.
