New metal phthalocyanine type cpds. derived from heterocyclic cpds. - forming electroconductive system useful e.g. as battery electrode, shield material etc.

摘要

New metal phthalocyanine-type cpds. (I) derived from heterocyclic cpds. contain an element of formula (Ia) in electrically neutral or cationic form. R is the divalent gp. of a heterocyclic cpd., selected from thiophene, pyrrole, benzothiophene, indole, bi- and polythienyl, bi- and polypyryl, bis-indole and indol-2,3-dione, Me is Cu, Fe, Mg, Zn, Ni, Co, Pr, Eu or Sm. (I) can be prepd. (not claimed) by the method described in GB 4464673. Examples are given in the text. USE/ADVANTAGE - (I) form electroconductive systems and may be p-doped with anions and n-doped with cations to a conductivity of 10 power-3 to 100 S/cm. They are sandwich-type porphyrin systems with a central metal atom. Useful for electrodes in prim. and sec. batteries, in insulators e.g. thermoplastic plastics to give a conductive system, for photovoltaic elements, thermostable screening materials against electrostatic charge and electromagnetic radiation, reversible redox system and hydrogenation catalysts (e.g. in the prodn. of MeOH from CO and H2).
