Collection: Donor-Acceptor (DA) Type Monomers [Polymer/Macromolecule Semiconductor Building Blocks]

Donor-Acceptor (DA) Type Monomers [Polymer/Macromolecule Semiconductor Building Blocks] — this collection gathers donor-acceptor (D-A) type conjugated aromatic monomers, such as benzothiadiazole, thiophene, and diketopyrrolopyrrole derivatives equipped with reactive functional groups (boronate, bromo, or trimethylstannyl). This group serves as basic building blocks for conjugated semiconducting polymers.

These D-A monomers are used by materials and organic electronics researchers to construct conjugated polymers through cross-coupling reactions such as Suzuki or Stille, producing organic semiconductors applied in organic photovoltaics (OPV), organic thin-film transistors (OFET), and other optoelectronic materials. The combination of electron-donor units (thiophene) and electron-acceptor units (benzothiadiazole, diketopyrrolopyrrole) allows control of the band gap of the resulting polymer.

Pay attention to the type of end-group functionality (boronate ester, bromo, or trimethylstannyl), which determines the type of coupling reaction that can be used, as well as the length of the side alkyl chains, which affects monomer solubility. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.
