Collection: Benzothiadiazoles and Analogs [Small Molecule Semiconductor Building Blocks]

Benzothiadiazoles and Analogs [Small Molecule Semiconductor Building Blocks] — covers the benzothiadiazole core and benzoxadiazole and benzoselenadiazole analogs substituted with bromo, nitrile, or boronate groups, which are electron-deficient and conjugated. This class serves as the acceptor unit in the design of push-pull organic semiconductor molecules.

Bromo-benzothiadiazole derivatives and naphthobis(thiadiazole) tetraboronates are used by organic electronics researchers to construct donor-acceptor materials for organic solar cells and field-effect transistors via Suzuki or Stille coupling reactions. Benzoxadiazole and benzoselenadiazole analogs are used as comparison units to study the effect of heteroatoms on the electronic properties of conjugated molecules.
