    Abstract: The present invention provides novel polymer compounds and methods and processes for polymerizing and synthesizing the new polymers by post-modifying conjugated polymers bearing unsaturated functionalities. The post-modifications are facilitated by light-mediated initiators, thermal initiators, redox-based initiators, small molecule-based initiators, or a combination thereof. Syntheses and post-modifications are carried out to high conversion via thiol-ene “click” chemistry-based mechanisms. The products comprise monomeric, oligomeric, and polymeric materials with easily-accessible pendant functionalities which impart new, distinct, and/or improved properties.

    Abstract: The present invention provides novel methods and processes for polymerizing unsaturated substrates, such as alkyne bearing monomers, with arenes. The polymerizations are catalyzed by gold (Au) catalysts/complexes and/or other cocatalysts. The invention further provides novel structurally complex polymers prepared in high yield via an intermolecular polyhydroarylation mechanism. Such resulting products comprise oligomeric and polymeric materials with novel molecular architectures and microstructures, which subsequently impart unique properties. The invention includes both the synthesis methods and processes and the resulting compounds and compositions of matter.
