Application

2T8-CHO-Br is a key building block in the development of organic field-effect transistors (OFETs) and bulk heterojunction solar cells, where its conjugated backbone facilitates charge transport. The bromine moiety allows for further functionalization via cross-coupling reactions (e.g., Suzuki or Stille couplings), while the aldehyde group enables Schiff base formation or condensation reactions. Researchers also utilize it to synthesize π-extended polymers for flexible electronics due to its balanced solubility and processability.
