Reaction Steps
A solution of N-bromosuccinimide (NBS) (48 g; 0.27 mol) dissolved in DMF (160 ml) was slowly added to a solution of 3-dodecylthiophene (68 g; 0.27 mol) dissolved in DMF (110 ml). After the reaction solution was stirred for one day, 750 ml of water was added thereto. An organic material was extracted by using ethyl ether (3×300 ml), and washed with brine and water, and then the residual moisture was removed over anhydrous magnesium sulfate. After removing the solvent, the residue was distilled off under reduced pressure at 125° C./˜5 mmHg to obtain a product (84.85 g, yield of 94%).
