Synthesis and Langmuir-Blodgett studies of silicon-phthalocyanine oligomers: Potential templates for organizing electroactive monomers

Abstract : Several new phthalocyanine-polysiloxanes containing pyridine moieties with potential use for organizing electroactive monomers have been synthesized. The compounds are slightly soluble in organic solvents due to their polycationic nature. However, when soluble enough, these oligomers give Langmuir-Blodgett films macroscopically in-plane oriented in which the long axis of the rod-like molecules lies parallel to the dipping direction.
