Biological Activity
4,7‑dibromo‑5‑fluoro‑2,1,3‑benzothiadiazole (compound 13) is a fluorinated benzothiadiazole-based dibromo-substituted electron acceptor monomer. It can be incorporated into the conjugated polymer backbone via Stille polymerization, which downregulates the HOMO and LUMO energy levels of the polymer and is beneficial for improving the open-circuit voltage[1].
4,7-Dibromo-2,1,3-benzothiadiazole serves as a building block for the organic synthesis of conjugated polymers used in high-performance optoelectronic devices and polymer solar cells[1][2].
