Used in organic electronics, particularly in the synthesis of conjugated polymers for organic solar cells and thin-film transistors. Its boron-containing group enables cross-coupling reactions, especially Suzuki-Miyaura coupling, to build complex conjugated systems. The dodecyl chain improves solubility in organic solvents, aiding solution-based processing for device fabrication. Commonly employed in developing donor-acceptor copolymers to tune bandgap and enhance charge carrier mobility.
