Abstract:
The invention provides for polymer structures and their preparation and resulting novel functionalities including open-shell character and high intrinsic conductivity with wide-range tenability. Electrical conductivity can be further modulated by introducing or blending with materials, fillers, dopants, and/or additives. The materials or resultant composites of the invention can be processed by various techniques into different forms to realize multiple applications.
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.

Abstract:
Described herein are novel light absorbing conjugated polymeric electron donor materials for organic photovoltaic devices and other applications. In one embodiment, the polymer structure comprises a conjugated electron rich donor unit with an imine functionality at the bridgehead position and a conjugated electron deficient unit in the polymer backbone arranged in an alternating fashion. Monomers suitable for making the polymers, and devices utilizing the polymers, are also disclosed.
Abstract:
Metal-ligand combination initiators are provided which yield organometallic complexes capable of the polymerization of olefins to high molecular weight polymers. Additionally, these initiators also enable the copolymerization of olefins with functionalized comonomers. These organometallic complexes comprise of a late transition metal with a neutral chelating ligand that contains a Lewis basic functionality in conjugation with an electronically delocalized conduit extending from the metal to the functionality. This structural feature results in a highly active complex, which generates high molecular weight polymers with unique microstructures. Under particular conditions, the organometallic complexes provide for the living polymerization of monomers and comonomers.
