Abstract
Abstract Methods and formable compositions for fabricating electrically conductive articles comprising cofacially stacking organomacrocycles and as cofacially stacking phthalocyanines, in which a composition comprising a cofacially stacking phthalocyanine in strong Bronsted acid is formed into a desired shape such as a fiber or film, solidified by removal of the solvent, and provided in fractional valence state.
