Two novel steric polymeric phthalocyanines, with copper (CuPPc) and aluminum hybrid zinc (Al/ZnPPc) as the central atoms, were synthesized by the cyclic condensation of tetrahedral tetra-phthalonitriles. The IR and UV-VIS spectra of the synthesized polymers indicated a moderate degree of polymerization, somewhere between the monomeric phthalocyanine and planar covalent polymer. Good thermal stability and a high metallic content of CuPPc and Al/ZnPPc were verified by TGA and ICA-AAS methods. The metallic atoms were distributed uniformly and exhibited different binding features with -CN, -O, -N in the polymer, as indicated by EDS and XPS analysis. High electrical conductivity was observed before and after iodine doping compared to the normal polymeric phthalocyanine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
