This study explores the design and synthesis of small molecules specifically tailored for organic solar cells, aiming to enhance their solubility, film-forming properties, and thermal stability through strategic material design. By achieving these improvements, we sought to advance the technology of organic solar cells. We successfully designed and synthesized a triangular disc-shaped small molecule material with benzotrithiophene as the core. To accurately determine the structure and properties of the target compound, we employed advanced characterization techniques, including TGA, NMR, and DSC. The results confirmed that the material exhibited high purity, thermal stability, and solubility. These remarkable attributes suggest significant potential for the material's use as an active layer in solar cells, paving the way developing of high-performance organic solar cells and opening new avenues in the field.
