The construction of three-dimensional (3D) covalent organic frameworks (COFs) remains challenging due to the limited types of organic building blocks. With octahedral TiIV complex as the building unit, this study reports on the first 3D anionic titanium-based COF (Ti-COF-1) with an edge-transitive (6, 4)-connected soc topology. Ti-COF-1 exhibits high crystallinity, superior stability, and large specific
由于有机构建块的类型有限,三维 (3D) 共价有机框架 (COF) 的构建仍然具有挑战性。本研究以八面体 Ti IV复合物作为构建单元,报道了第一个具有边缘传递 (6, 4) 连接的soc拓扑结构的3D 阴离子钛基 COF ( Ti-COF-1 ) 。Ti-COF-1具有高结晶度、优异的稳定性和大比表面积(1000.4 m 2 g -1)。此外,Ti-COF-1在紫外光谱中具有宽吸收带,光能隙为 1.86 eV,对梅尔温加成反应具有高光催化活性。这项研究展示了设计 3D 功能 COF 的有吸引力的策略。
