Bisaxially coordinated (phthalocyaninato) metal compounds with azobispyridine

Summary form only given. The quest for organic and polymeric conductors is of great scientific interest and has spurred research into their electrical, optical, magnetic, and biological properties. Hanack et al. reported that phthalocyaninato metal compounds which were polymerized via bridging heterocyclic amines, have excellent electrical properties. In this paper, the synthesis and properties of new azopyridines-bridged polymers of phthalocyaninato metals are presented. New bisaxially coordinated (phthalocyaninato) metal compounds were synthesized by melting azopyridines and phthalocyaninato metals such as (phthalocyaninato)iron(II) and (phthalocyaninato)cobalt(II), then were purified by sublimation. These complexes were characterized by using NMR spectra, UV-Vis spectra, and TG/DTA. PcML/sub 2/ and (PcML)n [PcM:phthalocyaninato metal, L:azobispyridine ligand] were found to be synthesized by melting the mixture. Additionally, electrical properties of these spin-coated and Langmuir-Blodgett films were investigated.
