Abstract

Peripheral substitution with bulky or long-chain groups is the most efficient way to overcome the problem of low solubility of the phthalocyanine ring systems in organic solvents. In the present work the synthesis of alkoxy substituted metallophthalocyanines with iron(III), palladium(II) and platinum(II) as central metal atom, respectively, is describe. The iron compounds were used to prepare bisaxially coordinated complexes and oligomers with, e.g., 2,3,5,6-tetramethyldiisocyanobenzene (me 4dib) as bridging ligand. Furthermore a new method to prepare bisaxially complexes of [tetra(t-butyl)phthalocyaninato]ruthenium(II), (t-Bu) 4PcRuL 2, which are considered as precursors of pure (t-Bu) 4PcRu is reported.
