In the past decade, polymer solar cells (PSCs) have attracted considerable attention for their unique advantages over traditional silicon-based solar cells, such as low cost, light weight, and the potential for making flexible large area devices by roll-to-roll manufacturing. Bulk heterojunction(BHJ) films has been dominated by polymeric donor materials, as they typically have better film-forming characteristics and film morphology than their small-molecule counterparts. Small molecules do not suffer from batch to batch variations, broad molecular-weight distributions, end-group contamination, or difficult purification methods, which can be significant problems for polymeric materials. Three small organic molecules, 5-hexyl-2,2'-bithiophene (HS5431), benzo[b]thiophene(HS5438) and tri phenyl amine(HS5439), with 2,2-dimethyl-2H-benzimidazole unit as new electron-deficient unit, were synthesized by Suzuki coupling reaction. The spectra of HS5431 and HS5439 in the solid thin films show absorption bands with maximum peaks at 399, 617 and 378, 602 nm.
