The on-surface conversion process from boroxine-linked covalent organic frameworks (COFs) to boronate ester-linked COFs is triggered and catalyzed at room temperature by an electric field and monitored with scanning tunneling microscopy (STM). The adaptive behavior within the generated dynamic covalent libraries (DCLs) was revealed, providing in-depth understanding of the dynamic network switching process.
在室温下，电场触发并催化了从硼氧环连接的共价有机框架（COF）到硼酸酯连接的COF的表面转化过程，并通过扫描隧道显微镜（STM）进行监测。揭示了生成的动态共价库（DCL）中的自适应行为，从而深入了解动态网络切换过程。
