2026-03-30 Construction of Clathrochelate-Bridged Covalent Organic Frameworks via Coordinate and Covalent Bonding doi:10.57760/sciencedb.30974 en we establish a synergistic co-assembly strategy integrating metal-ligand coordination with dynamic covalent B−O−N linkages for one-pot synthesis of a three-dimensional clathrochelate-bridged COF (Fe-CC-COF). Using an oxime ligand, FeCl2, and a tetrahedral boronate under kinetically synchronized conditions, we achieved high crystallinity and porosity. X-ray absorption fine structure (XAFS) spectroscopy confirmed well-defined FeN6 coordination. The framework exhibits reversible transitions between chelate-linked and metal-cage configurations and allows post-synthetic incorporation of diverse metal ions (M = Co2+, Ni2+, Cu2+, Zn2+), expanding the M-CC-COF family. covalent organic framework (COF); clathrochelate; B−O−N linkage; FeN6; ion cage Pengzhong Shi Yingjun Qiao Da Lei Zhong Liu PUBLIC https://opendatacommons.org/licenses/by/1-0/ dataset Science Data Bank
