已知硼酸酯简单地通过在中性条件下混合硼酸和醇形成，并且当使用1，2-或1，3-二醇作为醇时，平衡有利于硼酸酯。通过利用硼酸酯形成的动态性质，我们的小组成功地构建了独特的含硼的3D结构，如环状大环，笼和管，基于各种芳香族二-，三-或六硼酸的硼酸酯形成与最初设计的四醇1含有两组固定的1，2-二醇单元定向在引达省框架的同一面上。进一步探讨了所得硼酸盐的各种功能，揭示了该体系的特征。这个个人帐户描述了我们的自组装硼酸酯系统使用四醇1包括合成，主客体化学，动力学连接，特征动力学行为，和超分子催化。
Boronic esters are known to be formed simply by mixing boronic acids and alcohols under neutral conditions, and the equilibrium is in favor of the boronic esters when 1,2- or 1,3-diols are employed as alcohols. By utilizing the dynamic nature of the boronic ester formation, our group successfully constructed unique boron-containing 3D structures, such as ring-shaped macrocycles, cages, and tubes, based on the boronic ester formation of various aromatic di-, tri-, or hexaboronic acids with an originally designed tetrol 1 containing two sets of fixed 1,2-diol units oriented on the same face of an indacene framework. Various functions of the obtained boronates were further pursued to disclose the characteristic features of this system. This personal account describes our self-assembled boronate system using tetrol 1 including synthesis, host-guest chemistry, kinetic connection, characteristic dynamic behaviors, and supramolecular catalysis.
