Gel-phase materials are generated when molecular building blocks assemble into nanoscale architectures, usually 'one-dimensional' fibrils, which hierarchically assemble into bundles and subsequently form an entangled sample spanning network, capable of preventing the flow of bulk solvent. This tutorial review explores the vital role of chirality in gel formation. In particular, we focus on how fundamental self-assembly processes can translate molecular scale chiral information into nanoscale architectures, and then into the macroscopic behaviour of the gel. Chiral molecular gels have potential applications in nanofabrication and as addressable functional nanomaterials.
当分子构建单元组装成纳米级结构时,凝胶相材料就会生成,这些结构通常是“一维”纤维,它们会分层组装成束,随后形成一个缠结的样品跨越网络,能够阻止大量溶剂的流动。本教程综述探讨了手性在凝胶形成中的重要作用。特别是,我们关注基本的自组装过程如何将分子尺度的手性信息转化为纳米级结构,进而转化为凝胶的宏观行为。手性分子凝胶在纳米制造以及作为可寻址功能纳米材料方面具有潜在应用。
