Abstract
Abstract A process for the preparation of electrically conductive products which are stable to air and have conductivities greater than 1 ×10 -3 S/cm, by reacting a cation of a metal of group VII or VIII or of sub-group I of the periodic table with an organic chelating compound to give a metal chelate and oxidizing the latter to form a oxidized product, wherein the organic chelating compound is a 1,9-substituted phenalene of the formula I ##STR1## where X is O, NH, S, Se or Te and Y is OH, NH 2 or SH. The electrically conductive products are useful for the production of solar cells, the conversion and fixing of radiation, the production of electrical and magnetic switches and the antistatic treatment of plastics.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A process for the preparation of electrically conductive products which are stable to air and have conductivities greater than 1×10 -3 S/cm, said process comprising: reacting, in solution, a cation of a metal selected from the group consisting of Mn, Tc, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and Cu, which metal cation is employed in the form of a salt, with a 1,9-substituted phenalene of the general formula (I) ##STR6## where X is O, NH, S, Se or Te and Y is OH, NH 2 or SH, as organic chelating compound to give a metal chelate; isolating said metal chelate from said solution, and then oxidizing the said metal chelate with an oxidizing agent selected from the group consisting of AsF 5 , SbF 5 , SbCl 5 , chlorine, bromine, and iodine to form said electrically conductive product.
Claim 2
Dependent Claim
142 words
A process for the preparation of electrically conductive products which are stable to air and have conductivities greater than 1×10 -3 S/cm, said process comprising: reacting, in solution, a cation of a metal selected from the group consisting of Mn, Tc, Re, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and Cu, which metal cation is employed in the form of a salt, with a 1,9-substituted phenalene of the general formula (I) ##STR6## where X is O, NH, S, Se or Te and Y is OH, NH 2 or SH, as organic chelating compound to give a metal chelate; isolating said metal chelate from said solution, and then oxidizing the said metal chelate with an oxidizing agent selected from the group consisting of AsF 5 , SbF 5 , SbCl 5 , chlorine, bromine, and iodine to form said electrically conductive product.
Claim 3
Dependent Claim
29 words
The process of claim 1 wherein the oxidizing agent is selected from the group consisting of AsF 5 , SbF 5 , SbCl 5 , chlorine, bromine and iodine.
