Phthalocyanine compounds have several applications, in particular energy storage in electrochemical double layer capacitors. Several polymeric metal tetraaminophthalocyanines (T4APc) have been prepared and their storage capacities exploited. Exploring the electropolymerization of amine-functionalized metallophthalocyanine, specifically cobalt (II), nickel (II) and copper (II), the cycle life, film growth and charge/discharge rates these polymers and a copolymer containing different ratios of copper and nickel tetraaminophthalocyanine film are compared and contrasted. Synthesized cobalt tetraaminophthalocyanine did not contain electronic conductivity as expected according to literature. Copolymers of nickel and copper T4APc seem to display the most potential for supercapacitance use. Future directions include attempting to form stable films in industrial solvents like propylene carbonate using bridging ligands and a continued investigation into copolymers of tetraamino metallophthalocyanines (MT4APc).
