SYNTHESIS AND PROPERTIES OF SOLUBLE METLLOPHTHALOCYANINES

Peripheral substitution with bulky or long-chain groups is the most ef ficient way to overcome the problem of low solubility of the phthalocy anine ring systems in organic solvents. In the present work the synthe sis of alkoxy substituted metallophthalocyanines with iron(III), palla dium(II) and platinum(II) as central metal atom, respectively, is desc ribed. The iron compounds were used to prepare bisaxially coordinated complexes and oligomers with, e.g., 2,3,5,6-tetramethyldiisocyanobenze ne (me4dib) as bridging ligand. Furthermore a new method to prepare bi saxially complexes of [tetra(t-butyl)phthalocyaninato]ruthenium(II), ( t-Bu)4PcRuL2, which are considered as precursors of pure (t-Bu)4PcRu i s reported.
