| Abstract: | This Letter describes an efficient method for constructing a C3-symmetric [4]rotaxane through hydrogen bond-guided self-assembly and boroxine formation. The reactions proceed under mild conditions in solution, with entropically driven forces promoting the formation of the [4]rotaxane. |
| Keywords: | Dynamic covalent chemistry Rotaxane Hydrogen bonding Boroxine |
