We report a direct one-pot route for the preparation of supramolecules from simple polyacetylene diblock copolymers synthesized by mild ring-opening metathesis polymerization of cyclooctatetraene. This in situ nanoparticlization of conjugated polymer (INCP) approach is advantageous over conventional self-assembly processes because this method does not require any tedious postsynthetic treatments. Also, this direct approach provides intriguing supramolecules with a unique nanostructure resembling a caterpillar. Furthermore, the new supramolecules are highly stable adducts because the polyacetylene core block provides an exceptionally strong driving force for the self-assembly. Even though pristine polyacetylene is unstable in air, the polyacetylene segment in the nanocaterpillar is very stable because it is protected within the shell of the supramolecule.

由温和开环复分解聚合合成的聚乙炔二嵌段共聚物直接原位一锅法制备稳定的纳米毛虫

我们报告了一种从简单的聚乙炔二嵌段共聚物制备超分子的直接一锅法，该共聚物是通过环辛四烯的温和开环复分解聚合反应合成的。这种共轭聚合物原位纳米颗粒化 (INCP) 方法优于传统的自组装工艺，因为该方法不需要任何繁琐的合成后处理。此外，这种直接方法提供了具有类似毛毛虫的独特纳米结构的有趣超分子。此外，新的超分子是高度稳定的加合物，因为聚乙炔核心嵌段为自组装提供了异常强大的驱动力。尽管原始的聚乙炔在空气中不稳定，
