A polybenzodifuran ladder polymer is disclosed.

A novel monomer design for the synthesis of PPE-type polymers containing conjugated segments of well-defined length connected by flexible linkers under Sonogashira reaction conditions is presented. The resulting polymers retain the photophysical properties of a fully conjugated PPE. The extent of incorporation of the flexible units along the backbone is governed by the comonomer feed ratio and can be varied in a statistically predictable fashion.

“Black” photoactive materials that comprise synthetic eumelanin polymers are provided, as are methods of making and using the polymers. The synthetic eumelanin polymers are made from the plant oil vanillin, and exhibit defined structural and chemical characteristics (e.g. homogeneity, solubility, etc.) that make them suitable for use in devices that require photoactive materials, such as solar cells.

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.

The invention relates to a method for the preparation of a layer containing a plurality of linear carbyne chains, the method comprising (a) applying laser ablation on a piece of shungite in a liquid, followed by laser irradiation of the resultant carbon structures within the liquid in the presence of stabilizing metal nanoparticles, thereby to form a colloidal solution; and (b) subjecting at least a portion of said colloidal solution to AC voltage while the solution is allowed to dry, thereby to create a two-dimensional layer containing a plurality of carbyne chains.

Described are a carbon-iodine conjugated polymer and preparation thereof, an imaging marker thereof, and uses thereof for preparing a localization marker, and belongs to the technical field of imaging markers. The conjugated structure enables the polymer to have strong absorption in a visible light region, and high iodine content of up to 84.1% corresponds to the strong imaging ability thereof. During surgery, on the basis of the dual guidance of a polymer-based image marker and naked eye observation, the marker can better facilitate determination of tumor resection margins, achieving precise resection of tumors and minimizing damage to surrounding normal tissues. During cyberknife-based treatment, the polymer can replace clinical gold markers to provide ray marker guidance. Absence of metal artifacts improves ray imaging quality and the accuracy of radiation dose distribution, good biocompatibility enhances the stability of the relative position of the marker, and radiotherapy side effects can be further reduced.
