Rhodium-Catalyzed Polymerization Of Phenylacetylene And Its Derivatives

摘要

The present report overviews relevant aspects of rhodium-catalyzed polymerization of phenylacetylenes and substituted acetylene monomers. The π-conjugated polymers obtained through this catalytic homogeneous process are very interesting because of their outstanding electronic, optical and structural properties. The employed rhodium-based catalysts span from simple and well-defined mononu-clear complexes to complex binary or even ternary catalytic systems. Extensive fine-tuning of the electronic and steric properties of the catalysts has allowed tailoring the synthesis of conjugated polymers using living polymerization processes. Additionally, recent detailed studies concerning the mechanism of phenylacetylene polymerization are enlightened.
