To triphenylphosphine dibromide (2.3 g, 5.5 mmol), distilled dichloromethane (15 ml) was added under a nitrogen atmosphere, to dissolve. Then, a solution, in which {3-(triallylsilyl)propyl}(methoxy)dimethylsilane (32) (1.5 g, 5.0 mmol) is dissolved in distilled dichloromethane (5 ml), was added and stirred at room temperature for 5 hours to obtain {3-(triallylsilyl)propyl}(bromo)dimethylsilane (33). After stirring, glass beads which was treated with Piranha solution was added and stirred further at room temperature for 4 hours. Water was added to the reaction mixture to stop the reaction, then 10% hydrochloric acid was added until the salt was dissolved. After that, glass beads were filtered out and washed each three times with toluene, ethanol and diethyl ether, dried, obtaining a functional material (34) represented by the following chemical reaction equation.
