Ordered Nanostructures from the Self-Assembly of Reactive Coil-Rod-Coil Molecules

摘要

One of the most important challenges in the areas of nanomaterials and biomimetic chemistry is to construct supramolecular structures with well-defined shape and size by the self-assembly of programmed molecules.[1] Control of the supramolecular structure of self-assembling molecules and subsequent cross-linking of specific segments within the organized structure are an efficient way to produce robust organic nanomaterials while maintaining the precise size and shape of the self-assembled nanostructure.[2] Rod-shaped molecules containing flexible chains have been shown to self-assemble into a large variety of supramolecular structures, which include 3D bicontinuous cubic and 2D columnar structures.[3] To enhance the structural robustness of the self-assembled nanoarchitectures, we designed a coil-rod-coil molecule that contains polymerizable vinyl groups in the middle of the rod segment. Herein, we describe the self-assembling behavior of the coil-rod-coil molecule, 1 (Figure 1), which bears reactive divinyl groups in the center of the rod block, and the subsequent polymerization of 1 from an ordered state.
