The development of three-dimensional (3D) functionalized covalent-organic frameworks (COFs) is of critical importance for expanding their potential applications. However, the introduction of functional groups in 3D COFs remains largely unexplored. Herein, we report the first example of 3D Salphen-based COFs (3D-Salphen-COFs) and their metal-containing counterparts (3D-M-Salphen-COFs). These Salphen-based COFs exhibit high crystallinity and specific surface area in addition to excellent chemical stability. Furthermore, the Cu(II)-Salphen COF displays high activity in the removal of superoxide radicals. This study not only presents a new pathway to construct 3D functionalized COFs but also promotes their applications in biology and medicine.
三维（3D）功能化共价有机骨架（COFs）的发展对于扩大其潜在应用至关重要。然而，在 3D COFs 中引入官能团在很大程度上仍未得到探索。在此，我们报告了首例三维席夫碱基 COFs（3D-Salphen-COFs）及其含金属对应物（3D-M-Salphen-COFs）。这些席夫碱基 COFs 除了具有优异的化学稳定性外，还表现出高结晶度和比表面积。此外，Cu（II）-Salphen COF 在超氧自由基的去除中表现出高活性。本研究不仅为构建 3D 功能化 COFs 提供了新途径，而且促进了它们在生物学和医学中的应用。
