A series of free-standing large-area metalloporphyrin-based COF films, connected through dynamic covalent acylhydrazone bonds, are synthesized by liquid-air interfacial polymerization. These films are smooth, dense, uniform, and defect free, and display high hydrolytic and mechanical stability. The Co-based films are active for electrocatalytic oxygen reduction and evolution reactions and show promising applications in flexible Zn-air batteries.
