Boronate dynamic nanostructures (BDNs), featuring the use of dynamic boronate bonds, have shown great promise for various applications, as they not only combine the robustness of covalent bonds and the error-correction capability of noncovalent interactions, but also integrate into the unique room-temperature dynamic reversibility and multi-stimuli responsiveness. However, the construction of BDNs with specific morphologies and properties is essential but still remains an art rather than a science, due to a limited understanding of the formation mechanism and morphology control of BDNs. Herein, a systematic investigation of the formation of BDNs by using 30 different building blocks is performed. BDNs in diverse dimensions and shapes (such as nanospheres, nanoflowers, and previously unreported nanowires, nanorods, nanocanes and nanobelts) are obtained. The crucial impact of the composition and structure of building blocks on the BDN morphogenesis, such as (I) the type of linking group; (II) the type of spacer; (III) spacer length; (IV) spacer flexibility/rigidity; and (V) interchain interaction, is clearly demonstrated. Furthermore, the morphology–structure–property relationship of BDNs is also assessed to provide more information for future applications. Undoubtedly, this research provides guiding principles for the manipulation of the morphologies and properties of BDNs.

硼酸盐动态纳米结构的形貌控制和性能设计†

硼酸动态纳米结构（BDN）具有动态硼酸酯键的用途，已显示出对各种应用的广阔前景，因为它们不仅结合了共价键的坚固性和非共价相互作用的纠错能力，而且还集成到了独特的房间中温度动态可逆性和多刺激响应。然而，由于对BDN的形成机理和形态控制的了解有限，因此具有特定形态和特性的BDN的构建是必不可少的，但仍然是一门艺术，而不是一门科学。在本文中，通过使用30种不同的构建基块对BDN的形成进行了系统的研究。各种尺寸和形状的BDN（例如纳米球，纳米花以及以前未报道的纳米线，纳米棒，纳米藤条和纳米带）。结构单元的组成和结构对BDN形态发生的关键影响，例如（I）连接基团的类型；（二）垫片的种类；（三）垫片长度；（四）垫片的柔韧性/刚性；（V）链间相互作用，已得到明确证明。此外，还评估了BDN的形态，结构和属性关系，以为将来的应用提供更多信息。无疑，这项研究为操纵BDN的形态和特性提供了指导原则。还评估了BDN的形态，结构和属性之间的关系，以为将来的应用提供更多信息。无疑，这项研究为操纵BDN的形态和特性提供了指导原则。还评估了BDN的形态，结构和性质之间的关系，以为将来的应用提供更多信息。无疑，这项研究为操纵BDN的形态和特性提供了指导原则。
