実験手順
0.5 g of 5-formyl-2,2':5',2"-terthiophene was dissolved in 20 ml of THF and stirred at room temperature, followed by adding 0.034 g of NaBH4 and stirred for 2 hours. After the reduction was completed, 50 ml of water was added. The solution was then extracted with chloroform, dried over anhydrous Na2SO4, filtered and condensed. The yellowish powder was thus obtained and the melting point thereof was 151°-152° C. (yield was 97%).
