Collection: Polymer/Macromolecule Semiconductor Building Blocks

Polymer/Macromolecule Semiconductor Building Blocks — a collection of donor, acceptor, and donor-acceptor type monomers based on thiophene, fluorene, and benzodithiophene structures, as well as boronate and stannyl groups, that serve as building blocks for polymer semiconductors. These compounds are designed for cross-coupling reactions in forming long conjugated chains.

These building blocks are used by functional materials researchers to synthesize semiconducting polymers and macromolecules via Suzuki or Stille coupling reactions, utilizing boronate ester and trimethylstannyl groups as reaction sites. Benzodithiophene and benzothiadiazole derivatives are commonly used in the development of organic semiconductor materials for electronic applications such as transistors and organic photovoltaic cells.

Pay attention to monomer purity, regioselectivity of reactive groups (boronate or stannyl), and the length of side alkyl chains, which affect solubility during polymerization. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
