Description

4,7-Bis(5-octylthiophen-2-yl)benzo[c][1,2,5]thiadiazole features a rigid, electron-deficient benzo[c][1,2,5]thiadiazole core flanked by octylthiophene units, delivering enhanced solubility and film-forming properties. This structure promotes efficient charge transport in organic semiconductors, enabling high-performance solution-processed devices.

Application

4,7-Bis(5-octylthiophen-2-yl)benzo[c][1,2,5]thiadiazole serves as a high-performance electron-deficient building block in organic electronics. Its fused benzo[1,2,5]thiadiazole core enables strong intramolecular charge transfer when paired with electron-rich thiophene units. The octyl side chains enhance solubility and processability, facilitating solution-phase fabrication of semiconducting polymers and small-molecule active layers in organic field-effect transistors and solar cells.
