A Capping‐assisted Strategy for Synthesis of Glass‐like Carboxylate‐based Coordination Polymers

to form a boundary-free continuous internal structure. The as-prepared Cu-BTC g-CP exhibited an approximately similar fine structure like its crystalline counterpart (HKUST-1), which facilitated solvent and thermal-induced crystallization. Due to the internal structure continuity, the g-CP possesses ceramic-like hardness and wear resistance and plastic-like resilience. This capping-assisted strategy has been successfully extended to Ni-BTC and Fe-BTC systems under mild conditions and thus presenting a general method for the formation of glass-like carboxylate-based CPs.
