位于低分子量离散分子和高分子量分散聚合物之间的精密低聚材料不仅在基础研究方面而且在各种应用方面都构成了一个不断增长的研究领域。在有机硅（聚硅氧烷）材料领域，几个研究小组已经报道了用于合成离散的低聚硅氧烷的各种方法，但是仍然期望改进硅氧烷序列的控制。本文综述了我们最近的贡献，离散序列定义的低聚硅氧烷的控制迭代的B（C6F5）3催化反应的精确合成。由于可控迭代可以在一锅中进行，与其他报道的方法相比，可以更容易地合成各种离散序列限定的低聚硅氧烷。
Precise oligomeric materials that lie between the low-molecular-weight discrete molecules and high-molecu-lar-weight disperse polymers constitute a growing research area not only in terms of fundamental studies but also for various applications. In the field of silicone (polysiloxane) materials, several research groups have reported various methods for the synthesis of discrete oligosiloxanes but improvement in the control of siloxane sequences is still desirable. This review highlights our recent contributions to the precise synthesis of discrete sequence-defined oligosiloxanes by controlled iteration of B(C 6 F 5 ) 3 -catalyzed reactions. As controlled iteration can be performed in one pot, various discrete sequence-defined oligosiloxanes can be more readily synthesized in com-parison to the other reported methods.
