Ambient synthesis of metal-covalent organic frameworks with Fe-iminopyridine linkages

Highly crystalline Fe-COFs were constructed from the building blocks carrying pyridyl-aldehyde and triamine moieties in the presence of Fe(OTf)(2) and acetic acid under ambient conditions via a subcomponent assembly strategy. The spectral results prove the coordination of atomically distributed Fe(ii) ions with the nitrogen species of covalently formed iminopyridine linkages.
