精确控制一级化学结构，特别是复杂结构的一级化学结构，是理解功能大分子结构-性质关系的前提。本文报道了基于多面体低聚倍半硅氧烷(POSS)的三种具有复杂大分子结构的不对称巨型Gemini表面活性剂(AGGS)的合理设计和串联合成。在两个级联过程中(通常在5小时内)，可以合成AGGS，其中两个聚合物尾部的长度和两个POSS头部的身份可以独立地控制和系统地改变。它代表了一种方便、高效和模块化的方法，只需几个步骤就可以制备结构精确的巨型分子。这项研究扩大了可合成的巨型表面活性剂的范围，并有助于进一步向更复杂的大分子的结构进化。
Precise control of primary chemical structures, especially those of complex structures, is a prerequisite to understand the structure–property relationships of functional macromolecules. In this article, we report the rational design and tandem synthesis of three asymmetric giant gemini surfactants (AGGSs) of complex macromolecular structures based on polyhedral oligomeric silsesquioxane (POSS). In two cascading processes (typically within 5 hours), AGGSs can be synthesized where the length of the two polymer tails and the identity of the two POSS heads can be independently controlled and systematically varied. It represents a convenient, efficient, and modular way to prepare giant molecules with rigorous structural precision in only a few steps. This study expands the scope of synthetically available giant surfactants and facilitates further structural evolution toward even more complex macromolecules.
