Abstract

Metallophthalocyanines [PcM, Pc: phthalocyanine, M: Fe 2+ , Co 2+ ] were reacted with α-isocyanonaphthalene( α-in) and α-isocyanoanthracene (α-ia) to form monomeric complexes. The synthesis and coordination behaviour of the isocyanides as a ligand (L) are discussed. All the products were characterized by spectroscopic methods and instrumental analysis. The electrical conductivities of these complexes, which were not treated with dopant, were attributed to the metal-ligand electron delocalization in the PcML2 complexes. The complexes have an enlarged macrocycle where the π-electron back donating ability of PcM is stronger than the σ-electron coordinating ability of the isonitrile ligands. Their electrical conductivities were measured as σRT = 2.1×10 -9 ~3×10 -10 S/cm. Also thermal stability was investigated in this study.
