Lattice-Matched Polyoxometalates Direct Crystallization of Cationic Covalent Organic Frameworks.
Cationic covalent organic frameworks (COFs) hold great potential for ion conduction and catalysis, yet poor crystallinity from interlayer electrostatic repulsion severely limits their performance. Herein, we demonstrate that lattice-matched polyoxometalates (POMs) as multifunctional counterions can direct the crystalli...
