Synthesis and properties of axially disubstituted monomeric and oligomericphthalocyaninato ruthenium(II) compounds

Phthalocyaninato ruthenium(II) has been complexed bisaxially with substitut ed and unsubstituted p-diisocyanobenzenes (dib) to form oligomers that are characterized spectroscopically. Their electrical conductivities lie in the low semiconducting range and the substituents on the bridging ligands have been found to considerably lower the electrical conductivity. A general sy nthesis for peripherally substituted phthalocyanines has been developed. Th e bisaxially coordinated substituted phthalocyaninato ruthenium(II) compoun ds prepared have been found to be soluble in common organic solvents enabli ng easy characterization of the materials.
