Participants

Reaction Steps

After dissolving 1-[(4-n-hexyloxy)phenyl]-2,5-bis(2-thienyl)pyrrole (205 mg) into N,N-dimetylformamide (30 ml), tetracyanoethylene (126 mg) was added thereto, and then they were stirred for 24 hours at room temperature. After addition of water thereinto, extraction by toluene was conducted. The obtained organic layer is dried over anhydrous sodium sulfate, and then condensation thereof under vacuum was conducted. Subsequently, the condensed substance is separated by silica gel column chromatography using toluene as eluent to obtain 1-[(4-n-hexyloxy)phenyl]-2-(2-thienyl)-5-(5-tricyanoethenyl-2-thienyl)pyrrole (212 mg, yield 83%). After recrystallization from a chloroform-hexane mixture solvent, crystals having a bronzy metallic luster were obtained. FIG. 1 is a photograph showing the appearance of the crystals. Further, physical properties thereabout are shown bellow.
