这篇专题文章重点介绍了使用硼酸的分级超分子的最新进展。硼酸可以与二醇及其具有动态共价官能团的同系物参与“点击反应”。通过全面探索多个硼酸附加分子和多个羟基对应物之间的多功能连续硼酸酯酯化键，不仅开发了多功能超分子聚合物，而且开发了结构明确的网络纳米结构。此外，正交的相互作用，如配价键的硼中心与刘易斯碱已导致形成分级纳米/微米结构。硼酸盐系统有可能被用作智能凝胶，化学传感器，电子活性架构，非均相催化剂，化学刺激响应系统的药物输送等材料在这里，我们充分讨论了硼酸的结构导向能力的可行性，从新的智能材料的产生的角度来看。
Current progress on hierarchical supramolecules using boronic acids has been highlighted in this feature article. Boronic acids can participate in "click reactions" with diols and their congeners with dynamic covalent functionality. By comprehensively exploring versatile sequential boronate esterification linkages between plural boronic acid-appended molecules and multiple hydroxyl counterparts, not only versatile supramolecular polymers but also structurally well-defined network nanostructures have been developed. In addition orthogonal interactions such as dative bonds of the boron center with Lewis bases have led to the formation of hierarchical nano/microstructures. Boronate systems have the potential to be used as materials for smart gels, chemosensors, active architectures for electronics, heterogeneous catalysts, chemical-stimulus responsive systems for drug delivery, etc. Here, we fully discuss the feasibility of the structure-directing ability of boronic acids from the standpoint of the generation of new smart materials.
