Abstract

In this study, polysilanes were synthesized by electroreduction with different monomers such as $CH_3HSiCl_2$, $PhSiCl_3$, $CH_3SiCl_3$ and $(CH_3)_2SiCl_2$ by Mg electrodes under ultrasonic radiation. The effects of monomers and additives (p-dibromobenzene (DBB), naphthalene (NAPH) and anthracene (ANTH)) on the reaction rate were investigated. Polymerization of $PhSiCl_3$ among the four monomers showed the highest rate. p-dibromobenzene (DBB) was proved the most effective additive. Based on the observations, some possible reaction mechanisms of the polymerization were proposed.

본 연구에서 초음파 조사하에서 Mg 전극을 사용하여 $CH_3HSiCl_2$, $PhSiCl_3$, $CH_3SiCl_3$ 및 $(CH_3)_2SiCl_2$와 같은 여러 가지 모노머를 가지고 전기환원법에 의하여 폴리실란을 합성하였다. 또한 반응속도에 있어서 모노머와 첨가제 (p-dibromobenzene (DBB), naphthalene (NAPH) 및 anthracene (ANTH))의 효과를 연구하였다. 네 종류의 모노머중에서 $PhSiCl_3$의 고분자화 반응은 아주 높은 반응속도를 보였다. 또한, p-dibromobenzene(DBB)는 가장 좋은 첨가제로 입증되었다. 이들 관찰에 근거하여 이들의 고분자화 반응에서 가능한 반응 메커니즘을 제시하였다.
