将脉冲激光束在惰性气氛中溅射石墨产生的等离子体，与一维链状聚甲基硅氧烷的蒸气束流反应，在产物中通过真空升华和重结晶分离出了两种单晶，经X射线衍射测定为具有(CH3SiO1.5)n(n=8，10)组成的硅氧烷，它们均具有多面体的三维笼状构型.通过色-质联用还检测到其它硅氧烷化合物，其中某些产物已表征为二维多环的构型.反应结果表明，经由激光等离子体的碰撞和能量传递，反应物的链状结构发生解离和进-步反应，经结构重组形成了多种不同组成和构型的产物.

A special synthetic reaction has been developed, in which vapor of the reactant interacts with the high temperature plasma generated by laser ablating a graphite target. By selecting chained methylsilicone as reactant, a series of methylsilsesquioxanes products with various structural configurations have been obtained. Among them, two products, which were separated by sublimation in high vacuum and recrystalization, were characterized by X-ray crystal diffraction as (CH3SiO1.5)n(n = 8, 10). Both of them are found to have three-dimensional cage structure. In addition, other products with double ring structure were detected by GC-MS analysis. The results demonstrate the potential application of the synthetic reaction. In the reaction described in this article, resulting from the collision and energy-transfer of the laser plasma, chain structure of the reactant dissociated and recombined to give the cage and ring structure of the products.
