実験手順
The synthesis of 2,5-di-n-hexyl-3,6-bis(5-bromo-thiophen-2-yl)pyrrolo[3,4-c]-pyrrole-1,4-dione is done in analogy to Zhou et al., Macromolecules 43 (2010) 821-826. 2,5-Di-n-hexyl-3,6-bis(5-bromo-thiophen-2-yl)pyrrolo[3,4-c]-pyrrole-1,4-dione (237 mg, 0.378 mmol) and copper(I)-cyanide (1.50 g, 17.0 mmol) are placed in a 25 mL-flask under argon. Dry DMF (10 mL) is added and the mixture is stirred at 130° C. for 4 h. The solvent is removed under reduced pressure and the residual solid is extracted with chloroform (250 mL). After removing the solvent the crude product is purified by column chromatography (dichloromethane). A violet solid is obtained (52 mg, 27%).
